A vulnerability in the Linux kernel's AF_PACKET TX_RING implementation has been resolved. The issue involves improper handling of vmalloc-backed TX_RING buffers, where skbs keep raw pointers to ring frames without preserving vmalloc mappings, potentially leading to use-after-free conditions. The fix defers freeing vmalloc TX_RING buffers until all skbs finish, ensuring safe memory access and preventing race conditions during ring replacement and teardown.
