Ubuntu 20.04 LTS : Linux kernel vulnerabilities (USN-5317-1)

high Nessus Plugin ID 158731

Language:

Synopsis

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

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5317-1 advisory.

 Nick Gregory discovered that the Linux kernel incorrectly handled network offload functionality. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-25636)

 Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that hardware mitigations added by ARM to their processors to address Spectre-BTI were insufficient. A local attacker could potentially use this to expose sensitive information. (CVE-2022-23960)

 Max Kellermann discovered that the Linux kernel incorrectly handled Unix pipes. A local attacker could potentially use this to modify any file that could be opened for reading. (CVE-2022-0847)

 Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that hardware mitigations added by Intel to their processors to address Spectre-BTI were insufficient. A local attacker could potentially use this to expose sensitive information. (CVE-2022-0001, CVE-2022-0002)

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.
