MediumCVSS 5.5/10Last modified Oct 21, 2026

Description

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.
