Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel vulnerabilities (USN-5729-1)

high Nessus Plugin ID 167767

Language:

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5729-1 advisory.

 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)

 Hsin-Wei Hung discovered that the BPF subsystem in the Linux kernel contained an out-of-bounds read vulnerability in the x86 JIT compiler. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2022-2905)

 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)

 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)

 Gwangun Jung discovered that the netfilter subsystem in the Linux kernel did not properly prevent binding to an already bound chain. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2022-39190)

 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)

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.
