Vulnerability from github – Published: 2024-08-17 09:30 – Updated: 2025-11-04 00:31In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix missing lock on sync reset reload
On sync reset reload work, when remote host updates devlink on reload actions performed on that host, it misses taking devlink lock before calling devlink_remote_reload_actions_performed() which results in triggering lock assert like the following:
