Linux Kernel Complex Rules Rehash Error Flow Vulnerability in net/mlx5 Component

A vulnerability in the Linux kernel's handling of complex rule rehashing within the net/mlx5 component can lead to a series of soft lock-ups or other problematic behaviors. When moving rules between matchers, the process should not fail. However, if it does, the error flow should allow the kernel to continue functioning, albeit with impaired steering rules. This vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability can cause a series of soft lock-ups or other problematic behaviors in the kernel, disrupting normal operations.

Remediation

Users can apply the patch available in the Linux kernel stable tree to address this vulnerability.
