Technical Description

In 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:

WARNING: CPU: 4 PID: 1164 at net/devlink/core.c:261 devl_assert_locked+0x3e/0x50

…
