Vulnerability from variot
Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-d10dcb615c8e.
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.

linux-azure 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.
Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems
Details:
USN-4287-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. This update provides the corresponding updates for the Linux kernel for Microsoft Azure Cloud systems for Ubuntu 14.04 ESM.
It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. (CVE-2019-14615)
It was discovered that the Atheros 802.11ac wireless 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-2019-15099)
It was discovered that the HSA Linux kernel driver for AMD GPU devices did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service. (CVE-2019-16229)
It was discovered that the Marvell 8xxx Libertas WLAN device driver in the Linux kernel did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service. (CVE-2019-16232)
It was discovered that a race condition existed in the Virtual Video Test Driver in the Linux kernel. An attacker with write access to /dev/video0 on a system with the vivid module loaded could possibly use this to gain administrative privileges. (CVE-2019-18683)
It was discovered that the Renesas Digital Radio Interface (DRIF) driver in the Linux kernel did not properly initialize data. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2019-18786)
It was discovered that the Afatech AF9005 DVB-T USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-18809)
It was discovered that the btrfs file system in the Linux kernel did not properly validate metadata, leading to a NULL pointer dereference. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2019-19057)
It was discovered that the crypto subsystem in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19062)
It was discovered that the Realtek rtlwifi USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19063)
It was discovered that the RSI 91x WLAN device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19071)
It was discovered that the Atheros 802.11ac wireless USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19078)
It was discovered that the AMD GPU device drivers in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19082)
Dan Carpenter discovered that the AppleTalk networking subsystem of the Linux kernel did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-19227)
It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle ioctl requests to get emulated CPUID features. An attacker with access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-19332)
It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle certain conditions. An attacker could use this to specially craft an ext4 file system that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19767)
Gao Chuan discovered that the SAS Class driver in the Linux kernel contained a race condition that could lead to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-19965)
It was discovered that the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-20096)
Mitchell Frank discovered that the Wi-Fi implementation in the Linux kernel when used as an access point would send IAPP location updates for stations before client authentication had completed. A physically proximate attacker could use this to cause a denial of service. (CVE-2019-5108)
It was discovered that a race condition can lead to a use-after-free while destroying GEM contexts in the i915 driver for the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (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.

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.

This update provides the corresponding updates for the Linux\nkernel for Microsoft Azure Cloud systems for Ubuntu 14.04 ESM. \n\nIt was discovered that the Linux kernel did not properly clear data\nstructures on context switches for certain Intel graphics processors. A\nlocal attacker could use this to expose sensitive information. \n(CVE-2019-14615)\n\nIt was discovered that the Atheros 802.11ac wireless USB device driver in\nthe Linux kernel did not properly validate device metadata. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash). (CVE-2019-15099)\n\nIt was discovered that the HSA Linux kernel driver for AMD GPU devices did\nnot properly check for errors in certain situations, leading to a NULL\npointer dereference. A local attacker could possibly use this to cause a\ndenial of service. (CVE-2019-16229)\n\nIt was discovered that the Marvell 8xxx Libertas WLAN device driver in the\nLinux kernel did not properly check for errors in certain situations,\nleading to a NULL pointer dereference. A local attacker could possibly use\nthis to cause a denial of service. (CVE-2019-16232)\n\nIt was discovered that a race condition existed in the Virtual Video Test\nDriver in the Linux kernel. An attacker with write access to /dev/video0 on\na system with the vivid module loaded could possibly use this to gain\nadministrative privileges. (CVE-2019-18683)\n\nIt was discovered that the Renesas Digital Radio Interface (DRIF) driver in\nthe Linux kernel did not properly initialize data. A local attacker could\npossibly use this to expose sensitive information (kernel memory). \n(CVE-2019-18786)\n\nIt was discovered that the Afatech AF9005 DVB-T USB device driver in the\nLinux kernel did not properly deallocate memory in certain error\nconditions. (CVE-2019-18809)\n\nIt was discovered that the btrfs file system in the Linux kernel did not\nproperly validate metadata, leading to a NULL pointer dereference. An\nattacker could use this to specially craft a file system image that, when\nmounted, could cause a denial of service (system crash). (CVE-2019-19057)\n\nIt was discovered that the crypto subsystem in the Linux kernel did not\nproperly deallocate memory in certain error conditions. \n(CVE-2019-19062)\n\nIt was discovered that the Realtek rtlwifi USB device driver in the Linux\nkernel did not properly deallocate memory in certain error conditions. (CVE-2019-19063)\n\nIt was discovered that the RSI 91x WLAN device driver in the Linux kernel\ndid not properly deallocate memory in certain error conditions. (CVE-2019-19071)\n\nIt was discovered that the Atheros 802.11ac wireless USB device driver in\nthe Linux kernel did not properly deallocate memory in certain error\nconditions.

(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). (CVE-2019-19332)\n\nIt was discovered that the ext4 file system implementation in the Linux\nkernel did not properly handle certain conditions. 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. (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. (CVE-2019-5108)\n\nIt was discovered that a race condition can lead to a use-after-free while\ndestroying GEM contexts in the i915 driver for the Linux kernel. 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. 8) - x86_64\n\n3. Description:\n\nThe kernel-rt packages provide the Real Time Linux Kernel, which enables\nfine-tuning for systems with extremely high determinism requirements. \n\nBug Fix(es):\n\n* RT: update RT source tree to the RHEL-8.2 tree (BZ#1708716)\n\n* KVM-RT guest fails boot with emulatorsched (BZ#1712781)\n\n* 8 vCPU guest need max latency \u003c 20 us with stress [RT-8.2] (BZ#1757165)\n\n* Request nx_huge_pages=N as default value to avoid kvm-rt guest large\nlatency spike [rt-8] (BZ#1788352)\n\n* RT: Add rpm Provide of \u0027kernel\u0027 to indicate that this is a kernel package\n(BZ#1796284)\n\n* [RHEL8] RT kernel signed by test certificate and not Red Hat Secure Boot\n(BZ#1806871)\n\nEnhancement(s):\n\n* update to the upstream 5.x RT patchset (BZ#1680161)\n\n4",
