[PATCH net V2 02/11] net/mlx5: HWS, Fix memory leak in hws_action_get_shared_stc_nic error flow
Posted by Mark Bloch 1 month, 1 week ago
From: Lama Kayal <lkayal@nvidia.com>

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.

Fixes: 504e536d9010 ("net/mlx5: HWS, added actions handling")
