Loading vulnerability…
CVE-2024-26802 is a denial-of-service flaw in the Linux kernel stmmac Ethernet driver’s workqueue lifecycle handling. When stopping the FPE workqueue, the driver destroys a non-NULL workqueue but does not clear its stored pointer. A subsequent suspend/resume sequence can encounter failed hardware setup when DMA initialization fails before the workqueue is recreated. If a later transmit timeout triggers adapter reset and release processing, the driver may attempt to destroy the stale workqueue pointer, resulting in a NULL-pointer dereference and kernel or module panic.
