- ========================================================================= Ubuntu Security Notice USN-5130-1 November 09, 2021
linux vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 ESM
Summary:
Several security issues were fixed in the Linux kernel. (CVE-2020-29660)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: linux-image-3.13.0-188-generic 3.13.0-188.239 linux-image-3.13.0-188-lowlatency 3.13.0-188.239 linux-image-generic 3.13.0.188.197 linux-image-lowlatency 3.13.0.188.197 linux-image-server 3.13.0.188.197 linux-image-virtual 3.13.0.188.197
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
CVE-2020-27815
A flaw was reported in the JFS filesystem code allowing a local
attacker with the ability to set extended attributes to cause a
denial of service.
CVE-2020-27825
Adam 'pi3' Zabrocki reported a use-after-free flaw in the ftrace
ring buffer resizing logic due to a race condition, which could
result in denial of service or information leak.
CVE-2020-27830

Olivier Benjamin and Pawel Wieczorkiewicz reported a use-after-free
flaw which can be triggered by a block frontend in Linux blkback. A
misbehaving guest can trigger a dom0 crash by continuously
connecting / disconnecting a block frontend. A local attacker can take advantage of
this flaw for memory corruption or privilege escalation.
CVE-2020-36158
A buffer overflow flaw was discovered in the mwifiex WiFi driver
which could result in denial of service or the execution of
arbitrary code via a long SSID value.
CVE-2021-3347
It was discovered that PI futexes have a kernel stack use-after-free
during fault handling. An unprivileged user could use this flaw to
crash the kernel (resulting in denial of service) or for privilege
escalation.
CVE-2021-20177
A flaw was discovered in the Linux implementation of string matching
within a packet. A privileged user (with root or CAP_NET_ADMIN) can
take advantage of this flaw to cause a kernel panic when inserting
iptables rules.

An\n attacker with access to a LUN and knowledge of Unit Serial Number\n assignments can take advantage of this flaw to read and write to any\n LIO backstore, regardless of the SCSI transport settings. \n\nCVE-2020-29568 (XSA-349)\n\n Michael Kurth and Pawel Wieczorkiewicz reported that frontends can\n trigger OOM in backends by updating a watched path. \n\nCVE-2020-29569 (XSA-350)\n\n Olivier Benjamin and Pawel Wieczorkiewicz reported a use-after-free\n flaw which can be triggered by a block frontend in Linux blkback. A\n misbehaving guest can trigger a dom0 crash by continuously\n connecting / disconnecting a block frontend. A local attacker can take advantage of\n this flaw for memory corruption or privilege escalation. \n\nCVE-2020-36158\n\n A buffer overflow flaw was discovered in the mwifiex WiFi driver\n which could result in denial of service or the execution of\n arbitrary code via a long SSID value. \n\nCVE-2021-3347\n\n It was discovered that PI futexes have a kernel stack use-after-free\n during fault handling. An unprivileged user could use this flaw to\n crash the kernel (resulting in denial of service) or for privilege\n escalation. \n\nCVE-2021-20177\n\n A flaw was discovered in the Linux implementation of string matching\n within a packet. A privileged user (with root or CAP_NET_ADMIN) can\n take advantage of this flaw to cause a kernel panic when inserting\n iptables rules. \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 4.19.171-2. \n\nWe recommend that you upgrade your linux packages. \n\nFor the detailed security status of linux please refer to its security\ntracker page at:\nhttps://security-tracker.debian.org/tracker/linux\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nj3wO/r/1gut/bK/OJnjmOB9J5OXP+cHxYtrhPqXFy2Hzkgj1CRU=\n=u23W\n-----END PGP SIGNATURE-----\n",

var-201911-0712
Vulnerability from variot
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

[slackware-security] Slackware 14.2 kernel (SSA:2020-008-01)
New kernel packages are available for Slackware 14.2 to fix security issues.
Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/linux-4.4.208/: Upgraded. IPV6_MULTIPLE_TABLES n -> y +IPV6_SUBTREES y These updates fix various bugs and security issues. Be sure to upgrade your initrd after upgrading the kernel packages. If you use lilo to boot your machine, be sure lilo.conf points to the correct kernel and initrd and run lilo as root to update the bootloader. If you use elilo to boot your machine, you should run eliloconfig to copy the kernel and initrd to the EFI System Partition.

Installation instructions: +------------------------+
Upgrade the packages as root:
upgradepkg kernel-*.txz
If you are using an initrd, you'll need to rebuild it.
For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2):
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.208-smp | bash
For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2):
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.208 | bash
Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 4.4.208-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.208 as the version.
If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting.
If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader.
If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition.

(CVE-2020-7053)
It was discovered that the B2C2 FlexCop USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15291)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: linux-image-4.15.0-1069-azure 4.15.0-1069.74~14.04.1 linux-image-azure 4.15.0.1069.55
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

"data": "An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

Most systems should run the SMP kernel (if they can)\nregardless of the number of cores the CPU has. If you aren\u0027t sure which\nkernel you are running, run \"uname -a\". If you see SMP there, you are\nrunning the SMP kernel and should use the 4.4.208-smp version when running\nmkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit\nsystems should always use 4.4.208 as the version. \n\nIf you are using lilo or elilo to boot the machine, you\u0027ll need to ensure\nthat the machine is properly prepared before rebooting. \n\nIf using LILO:\nBy default, lilo.conf contains an image= line that references a symlink\nthat always points to the correct kernel. No editing should be required\nunless your machine uses a custom lilo.conf. If that is the case, be sure\nthat the image= line references the correct kernel file. Either way,\nyou\u0027ll need to run \"lilo\" as root to reinstall the boot loader. \n\nIf using elilo:\nEnsure that the /boot/vmlinuz symlink is pointing to the kernel you wish\nto use, and then run eliloconfig to update the EFI System Partition. \n\n\n+-----+\n\nSlackware Linux Security Team\nhttp://slackware.com/gpg-key\nsecurity@slackware.com\n\n+------------------------------------------------------------------------+\n| To leave the slackware-security mailing list: |\n+------------------------------------------------------------------------+\n| Send an email to majordomo@slackware.com with this text in the body of |\n| the email message: |\n| |\n| unsubscribe slackware-security |\n| |\n| You will get a confirmation message back containing instructions to |\n| complete the process.

(CVE-2019-19078)\n\nIt was discovered that the AMD GPU device drivers in the Linux kernel did\nnot properly deallocate memory in certain error conditions. A local\nattacker could use this to possibly cause a denial of service (kernel\nmemory exhaustion). (CVE-2019-19082)\n\nDan Carpenter discovered that the AppleTalk networking subsystem of the\nLinux kernel did not properly handle certain error conditions, leading to a\nNULL pointer dereference. A local attacker could use this to cause a denial\nof service (system crash). (CVE-2019-19227)\n\nIt was discovered that the KVM hypervisor implementation in the Linux\nkernel did not properly handle ioctl requests to get emulated CPUID\nfeatures. An attacker with access to /dev/kvm could use this to cause a\ndenial of service (system crash). An attacker could use\nthis to specially craft an ext4 file system that, when mounted, could cause\na denial of service (system crash) or possibly execute arbitrary code. \n(CVE-2019-19767)\n\nGao Chuan discovered that the SAS Class driver in the Linux kernel\ncontained a race condition that could lead to a NULL pointer dereference. A\nlocal attacker could possibly use this to cause a denial of service (system\ncrash). (CVE-2019-19965)\n\nIt was discovered that the Datagram Congestion Control Protocol (DCCP)\nimplementation in the Linux kernel did not properly deallocate memory in\ncertain error conditions. An attacker could possibly use this to cause a\ndenial of service (kernel memory exhaustion). (CVE-2019-20096)\n\nMitchell Frank discovered that the Wi-Fi implementation in the Linux kernel\nwhen used as an access point would send IAPP location updates for stations\nbefore client authentication had completed. A physically proximate attacker\ncould use this to cause a denial of service. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2020-7053)\n\nIt was discovered that the B2C2 FlexCop USB device driver in the Linux\nkernel did not properly validate device metadata. A physically proximate\nattacker could use this to cause a denial of service (system crash). \n(CVE-2019-15291)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 14.04 ESM:\n linux-image-4.15.0-1069-azure 4.15.0-1069.74~14.04.1\n linux-image-azure 4.15.0.1069.55\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. \n\nReferences:\n https://usn.ubuntu.com/4287-2\n https://usn.ubuntu.com/4287-1\n CVE-2019-14615, CVE-2019-15099, CVE-2019-15291, CVE-2019-16229,\n CVE-2019-16232, CVE-2019-18683, CVE-2019-18786, CVE-2019-18809,\n CVE-2019-18885, CVE-2019-19057, CVE-2019-19062, CVE-2019-19063,\n CVE-2019-19071, CVE-2019-19078, CVE-2019-19082, CVE-2019-19227,\n CVE-2019-19332, CVE-2019-19767, CVE-2019-19965, CVE-2019-20096,\n CVE-2019-5108, CVE-2020-7053\n\n",

Vulnerability from variot
A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through 5.9.13. drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may allow a read-after-free attack against TIOCGSID, aka CID-c8bcd9c5be24. Vendors must CID-c8bcd9c5be24 It is published as.Information may be obtained. Bugs fixed (https://bugzilla.redhat.com/):
2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value
- ========================================================================== Ubuntu Security Notice USN-4752-1 February 25, 2021
linux-oem-5.6 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-oem-5.6: Linux kernel for OEM systems
Details:
Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered that legacy pairing and secure-connections pairing authentication in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. A physically proximate attacker could use this to impersonate a previously paired Bluetooth device. (CVE-2020-10135)
Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-14314)
It was discovered that the block layer implementation in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-15436)
It was discovered that the serial port driver in the Linux kernel did not properly initialize a pointer in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2020-15437)
Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490)
It was discovered that the NFS client implementation in the Linux kernel did not properly perform bounds checking before copying security labels in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)
It was discovered that the Rados block device (rbd) driver in the Linux kernel did not properly perform privilege checks for access to rbd devices in some situations. A local attacker could use this to map or unmap rbd block devices. A local attacker could use this to cause a denial of service. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. A privileged attacker could use this to cause a denial of service (kernel memory exhaustion). A local attacker in a guest VM could possibly use this to cause a denial of service (host system crash). A local attacker could use this to possibly cause a denial of service (system crash). A local attacker could use this to expose sensitive information (kernel memory). (CVE-2020-28588)
It was discovered that the framebuffer implementation in the Linux kernel did not properly perform range checks in certain situations. A local attacker could use this to expose sensitive information (kernel memory). A local attacker could use this to gain unintended write access to read-only memory pages. (CVE-2020-29368)
Jann Horn discovered that the mmap implementation in the Linux kernel contained a race condition when handling munmap() operations, leading to a read-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-29369)
Jann Horn discovered that the romfs file system in the Linux kernel did not properly validate file system meta-data, leading to an out-of-bounds read. An attacker could use this to construct a malicious romfs image that, when mounted, exposed sensitive information (kernel memory). A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-29661)
It was discovered that a race condition existed that caused the Linux kernel to not properly restrict exit signal delivery. A local attacker could possibly use this to send signals to arbitrary processes. (CVE-2020-35508)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: linux-image-5.6.0-1048-oem 5.6.0-1048.52 linux-image-oem-20.04 5.6.0.1048.44
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

Package : linux CVE ID : CVE-2020-27815 CVE-2020-27825 CVE-2020-27830 CVE-2020-28374 CVE-2020-29568 CVE-2020-29569 CVE-2020-29660 CVE-2020-29661 CVE-2020-36158 CVE-2021-3347 CVE-2021-20177 Debian Bug : 970736 972345 977048 977615
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
CVE-2020-27825
Adam 'pi3' Zabrocki reported a use-after-free flaw in the ftrace
ring buffer resizing logic due to a race condition, which could
result in denial of service or information leak.
CVE-2020-27830
Shisong Qin reported a NULL pointer dereference flaw in the Speakup
screen reader core driver.
CVE-2020-28374
David Disseldorp discovered that the LIO SCSI target implementation
performed insufficient checking in certain XCOPY requests. An
attacker with access to a LUN and knowledge of Unit Serial Number
assignments can take advantage of this flaw to read and write to any
LIO backstore, regardless of the SCSI transport settings.
CVE-2020-29568 (XSA-349)
Michael Kurth and Pawel Wieczorkiewicz reported that frontends can
trigger OOM in backends by updating a watched path. A
misbehaving guest can trigger a dom0 crash by continuously
connecting / disconnecting a block frontend.
CVE-2020-36158
A buffer overflow flaw was discovered in the mwifiex WiFi driver
which could result in denial of service or the execution of
arbitrary code via a long SSID value. A privileged user (with root or CAP_NET_ADMIN) can
take advantage of this flaw to cause a kernel panic when inserting
iptables rules.
For the stable distribution (buster), these problems have been fixed in version 4.19.171-2.
We recommend that you upgrade your linux packages.

A\nphysically proximate attacker could use this to impersonate a previously\npaired Bluetooth device. (CVE-2020-10135)\n\nJay Shin discovered that the ext4 file system implementation in the Linux\nkernel did not properly handle directory access with broken indexing,\nleading to an out-of-bounds read vulnerability. A local attacker could use\nthis to cause a denial of service (system crash). (CVE-2020-14314)\n\nIt was discovered that the block layer implementation in the Linux kernel\ndid not properly perform reference counting in some situations, leading to\na use-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash). (CVE-2020-15436)\n\nIt was discovered that the serial port driver in the Linux kernel did not\nproperly initialize a pointer in some situations. A local attacker could\npossibly use this to cause a denial of service (system crash). \n(CVE-2020-15437)\n\nAndy Nguyen discovered that the Bluetooth HCI event packet parser in the\nLinux kernel did not properly handle event advertisements of certain sizes,\nleading to a heap-based buffer overflow. A physically proximate remote\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2020-24490)\n\nIt was discovered that the NFS client implementation in the Linux kernel\ndid not properly perform bounds checking before copying security labels in\nsome situations. A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2020-25212)\n\nIt was discovered that the Rados block device (rbd) driver in the Linux\nkernel did not properly perform privilege checks for access to rbd devices\nin some situations. A local attacker could use this to map or unmap rbd\nblock devices. A local attacker could use this\nto cause a denial of service. A local attacker could use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. A privileged attacker\ncould use this to cause a denial of service (kernel memory exhaustion). A local attacker in a\nguest VM could possibly use this to cause a denial of service (host system\ncrash). A local attacker\ncould use this to possibly cause a denial of service (system crash). A local attacker\ncould use this to expose sensitive information (kernel memory). \n(CVE-2020-28588)\n\nIt was discovered that the framebuffer implementation in the Linux kernel\ndid not properly perform range checks in certain situations. A local\nattacker could use this to expose sensitive information (kernel memory). A local attacker could use\nthis to gain unintended write access to read-only memory pages. \n(CVE-2020-29368)\n\nJann Horn discovered that the mmap implementation in the Linux kernel\ncontained a race condition when handling munmap() operations, leading to a\nread-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash) or possibly expose sensitive information. \n(CVE-2020-29369)\n\nJann Horn discovered that the romfs file system in the Linux kernel did not\nproperly validate file system meta-data, leading to an out-of-bounds read. \nAn attacker could use this to construct a malicious romfs image that, when\nmounted, exposed sensitive information (kernel memory). A local attacker could use this to cause a denial of service\n(system crash) or possibly expose sensitive information (kernel memory). A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2020-29661)\n\nIt was discovered that a race condition existed that caused the Linux\nkernel to not properly restrict exit signal delivery. A local attacker\ncould possibly use this to send signals to arbitrary processes. \n(CVE-2020-35508)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 20.04 LTS:\n linux-image-5.6.0-1048-oem 5.6.0-1048.52\n linux-image-oem-20.04 5.6.0.1048.44\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. \n\nReferences:\n https://usn.ubuntu.com/4752-1\n CVE-2020-10135, CVE-2020-14314, CVE-2020-15436, CVE-2020-15437,\n CVE-2020-24490, CVE-2020-25212, CVE-2020-25284, CVE-2020-25641,\n CVE-2020-25643, CVE-2020-25704, CVE-2020-27152, CVE-2020-27815,\n CVE-2020-28588, CVE-2020-28915, CVE-2020-29368, CVE-2020-29369,\n CVE-2020-29371, CVE-2020-29660, CVE-2020-29661, CVE-2020-35508\n\nPackage Information:\n https://launchpad.net/ubuntu/+source/linux-oem-5.6/5.6.0-1048.52\n.

Summary
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

Summary
ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file.

Vulnerability from fkie_nvd
Published

Modified
2024-11-21 04:44
Severity ?
Summary
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.

Summary
In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption.

Summary
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780)

Vulnerability from fkie_nvd
Published
2020-01-16 16:15
Modified
2024-11-21 04:32
Severity ?
Summary
The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

Summary
The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

Summary
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.

Summary
ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file.

Summary
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780)

Summary
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

Summary
In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption.
