Ubuntu 22.04 LTS : Linux kernel (OEM) vulnerability (USN-6650-1)

medium Nessus Plugin ID 190940

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-6650-1 advisory.

 Zhenghan Wang discovered that the generic ID allocator implementation in the Linux kernel did not properly check for null bitmap when releasing IDs. A local attacker could use this to cause a denial of service (system crash).

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.
