CVE-2024-26802

CVE-2024-26802: In the Linux kernel stmmac driver, destroy_workqueue() drains the queue and clears the workqueue variable but does not set it to NULL, enabling a possible kernel/module panic if a cleared-but-non-NULL pointer is later used during resume/reset flows. The fix is to set the workqueue...
