In the Linux kernel, the following vulnerability has been resolved: afs: Fix potential null pointer dereference in afs_put_server afs_put_server() accessed server->debug_id before the NULL check, which could lead to a null pointer dereference. Move the debug_id assignment, ensuring we never dereference a NULL server pointer.
