CVE-2025-21675 is a vulnerability in the Linux kernel's mlx5 network driver where failure to clear the port select structure on error leads to double destruction of lag definers. This results in a kernel NULL pointer dereference and a crash. The issue occurs because stale values remain after definers are destroyed, causing repeated destruction attempts. The vulnerability has a medium severity score and impacts system availability due to kernel crashes.
