CVE-2026-43467

A flaw was found in the Linux kernel's mlx5core driver. A local user or process can trigger a system crash by attempting to move a network device to switchdev mode when the device does not support IPsec. This occurs because the kernel incorrectly tries to clean up IPsec resources that do not exis...
