| Doc Text: |
A use-after-free flaw was discovered in the Linux kernel’s mlx5e networking driver. The code erroneously cloned flow post action attributes a second time in mlx5e_tc_post_act_add() despite an earlier clone in mlx5e_clone_flow_attr_for_post_act(). This second clone is not properly updated during neighbor update operations, which can lead to use-after-free memory access when the stale attribute copy is dereferenced.
