A use-after-free vulnerability in the Linux kernel's io_uring implementation with SQPOLL mode has been resolved. The issue occurs because the sqpoll thread processes task_work independently, potentially freeing resources while another function still accesses them. This leads to a use-after-free condition detected by KASAN. The fix involves holding an RCU read lock during task_work addition and waiting for a grace period before freeing resources.
