How to fix?

Upgrade SLES:16.0.0 kernel-source to version 6.12.0-160000.6.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: HWS, Fix memory leak in hws_action_get_shared_stc_nic error flow

When an invalid stc_type is provided, the function allocates memory for shared_stc but jumps to unlock_and_out without freeing it, causing a memory leak.

Fix by jumping to free_shared_stc label instead to ensure proper cleanup.
