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

high Nessus Plugin ID 178648

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.

- An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2023-2124)

- A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem to crash the system or escalation of privilege. (CVE-2023-2176)

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.
