Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability has been resolved in the Linux kernel. The issue is related to the cleanup of CT before the cleanup of TC ct rules in the net/mlx5e module. The CT cleanup assumes that all tc rules were deleted first, but this is not the case for uplink, causing a problem. The fix involves reversing the order of init and cleanup, resulting in tc cleanup followed by ct cleanup.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
