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

net/mlx5e: Take state lock during tx timeout reporter

mlx5e_safe_reopen_channels() requires the state lock taken. The
referenced changed in the Fixes tag removed the lock to fix another
issue. This patch adds it back but at a later point (when calling
mlx5e_safe_reopen_channels()) to avoid the deadlock referenced in the
Fixes tag.
