CVE-2024-45019: net/mlx5e: Take state lock during tx timeout reporter
First published: Wed Sep 11 2024(Updated: )
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.
