Echo: linux: security update to 6.4.11-1

medium Tenable Self-Hosted Container Security Plugin ID 457130

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix crash on regular
 rq reactivation When the regular rq is reactivated after the XSK socket is closed it could be reading
 stale cqes which eventually corrupts the rq. This leads to no more traffic being received on the regular
 rq and a crash on the next close or deactivation of the rq. Kal Cuttler Conely reported this issue as a
 crash on the release path when the xdpsock sample program is stopped (killed) and restarted in sequence
 while traffic is running. This patch flushes all cqes when during the rq flush. The cqe flushing is done
 in the reset state of the rq. mlx5e_rq_to_ready code is moved into the flush function to allow for this.
 (CVE-2023-53394)

Solution

Update the linux library and its related packages to version 6.4.11-1 or later.
