Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.0-rc5 mlnx

Description A flaw exists in the net/mlx5 component of the Linux kernel related to delayed bond work cancellation. A missing call to cancel delayed work could lead to the execution of code on an already destroyed work queue, resulting in a kernel NULL pointer dereference. This can cause a system crash, as indicated by a kernel panic with a bug message. The issue was addressed by restoring the call to cancel delayed work sync() before destroying the workqueue.

Recommendations Update to a version of the Linux kernel newer than 6.0.0-rc5 mlnx.
