Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel vulnerabilities (USN-5728-2)

high Nessus Plugin ID 167920

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5728-2 advisory.

 Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42703)

 It was discovered that a race condition existed in the memory address space accounting implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41222)

 It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2022-20422)

 It was discovered that the KVM implementation in the Linux kernel did not properly handle virtual CPUs without APICs in certain situations. A local attacker could possibly use this to cause a denial of service (host system crash). (CVE-2022-2153)

 Hao Sun and Jiacheng Xu discovered that the NILFS file system implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2978)

 Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64 processors, the Linux kernel's protections against speculative branch target injection attacks were insufficient in some circumstances. A local attacker could possibly use this to expose sensitive information. (CVE-2022-29901)

 Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-3028)

 It was discovered that the Netlink device interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a use-after-free vulnerability with some network device drivers. A local attacker with admin access to the network device could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3625)

 It was discovered that the IDT 77252 ATM PCI device driver in the Linux kernel did not properly remove any pending timers during device exit, resulting in a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-3635)

 Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX storage controller driver in the Linux kernel did not properly handle certain structures. A local attacker could potentially use this to expose sensitive information (kernel memory). (CVE-2022-40768)

 Snke Huster discovered that a use-after-free vulnerability existed in the WiFi driver stack in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42719)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
