CVE-2019-5108

A flaw was found in the Linux kernel’s implementation of the WiFi station handoff code. An attacker within the radio range could use this flaw to deny a valid device from joining the access point.

6.5 (Medium)


                        
                          CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-440 - Expected Behavior Violation

Vendor Fix For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. https://access.redhat.com/errata/RHSA-2020:1493

Workaround At this time there is no known mitigations to this issue other than to install the updated kernel package.

CVE-2019-14895

A heap-based buffer overflow was discovered in the Linux kernel's Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.

8.0 (High)


                        
                          CVSS:3.0/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

CWE-122 - Heap-based Buffer Overflow

CVE-2019-14901

A heap overflow flaw was found in the Linux kernel's Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system.

8.8 (High)


                        
                          CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CWE-805 - Buffer Access with Incorrect Length Value

CVE-2019-15031

A flaw in the Linux kernel on the PowerPC platform, was found where a local user can read vector registers of other user processes (during a hardware interrupt). An attacker must start a transaction when the FPU operation begins or there is no leakage. Vector registers will become corrupted with values from the different local Linux processes, because of the missing check inside arch/powerpc/kernel/process.c. The highest threat from this vulnerability is confidentiality of data and availability of the system.

4.4 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L

CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor

Workaround When applicable rely on FPU emulation (for example by rebuilding the critical services code) instead of the hardware FPU.

CVE-2019-15099

A null pointer dereference flaw was discovered in the Linux kernel's implementation of the ath10k USB device driver. The vulnerability requires the attacker to plug in a specially crafted hardware device that present endpoint descriptors that normal ath10k devices do not recognize. System availability is the highest threat with this vulnerability.

4.3 (Medium)


                        
                          CVSS:3.0/AV:P/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

CWE-20 - Improper Input Validation

Workaround As the ath10k module will be auto-loaded when required, its use can be disabled by preventing the module from loading using the following instructions. On the command line, as root, execute the following command: # echo "install ath10k_usb /bin/true" >> /etc/modprobe.d/disable-ath10k_usb.conf The system will need to be restarted if the ath10k_usb module are loaded. In most circumstances, the kernel modules will be unable to be unloaded while the ath10k WiFi network interface is in use. If the system requires this module to work correctly, this mitigation may not be suitable. If you need further assistance, see KCS article https://access.redhat.com/solutions/41278 or contact Red Hat Global Support Services.

CVE-2019-15666

A flaw was found in the Linux kernel. When xfrm policy removal occurs a system crash could occur. These policy changes generally occur through the ip command or a netlink socket.

6.7 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

CWE-400 - Uncontrolled Resource Consumption

CVE-2019-19922

A flaw was found in the Linux kernel’s scheduler, where it can allow attackers to cause a denial of service against non-CPU-bound applications by generating a workload that triggers unwanted scheduling slice expiration. A local attacker who can trigger a specific workload type could abuse this technique to trigger a system to be seen as degraded, and possibly trigger workload-rebalance in systems that use the slice-expiration metric as a measure of system health.

5.5 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

CWE-400 - Uncontrolled Resource Consumption

Workaround Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

CVE-2019-20054

A flaw was found in the Linux kernel’s implementation of dropping sysctl entries. A local attacker who has access to load modules on the system can trigger a condition during module load failure and panic the system.

5.1 (Medium)


                        
                          CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2019-20095

A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting the repeated connection attempts are attempted.

5.2 (Medium)


                        
                          CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H

CWE-772 - Missing Release of Resource after Effective Lifetime

Workaround As connecting to a wireless device is not automatic and initiated by a user, not connecting to rogue access points would prevent this flaw from being abused.

CVE-2019-19922 (GCVE-0-2019-19922)

Vulnerability from cvelistv5 – Published: 2019-12-22 19:07 – Updated: 2024-08-05 02:32

Summary

kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel; it only causes mismanagement of application execution.)

CVE-2019-15031 (GCVE-0-2019-15031)

Vulnerability from cvelistv5 – Published: 2019-09-13 12:45 – Updated: 2024-08-05 00:34

Summary

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c.

Severity ?

CVE-2019-5108 (GCVE-0-2019-5108)

Vulnerability from cvelistv5 – Published: 2019-12-23 18:55 – Updated: 2024-08-04 19:47

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.

Severity ?

7.4 (High)
