Ubuntu 23.04 : Linux kernel vulnerabilities (USN-6224-1)

high Nessus Plugin ID 178648

Language:

Synopsis

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

Description

The remote Ubuntu 23.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6224-1 advisory.

 It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2023-2124)

 Wei Chen discovered that the InfiniBand RDMA communication manager implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-2176)

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.
