Ubuntu 22.04 LTS : Linux kernel (OEM) vulnerability (USN-5799-1)

high Nessus Plugin ID 169905

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5799-1 advisory.

 Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.

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

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

Solution

Update the affected kernel package.
