  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nafs: Fix lock recursion\nafs_wake_up_async_call() can incur lock recursion.  The problem is that it\nis called from AF_RXRPC whilst holding the ->notify_lock, but it tries to\ntake a ref on the afs_call struct in order to pass it to a work queue - but\nif the afs_call is already queued, we then have an extraneous ref that must\nbe put... calling afs_put_call() may call back down into AF_RXRPC through\nrxrpc_kernel_shutdown_call(), however, which might try taking the\n->notify_lock again.\nThis case isn't very common, however, so defer it to a workqueue.  The oops\nlooks something like:\nBUG: spinlock recursion on CPU#0, krxrpcio/7001/1646\nlock: 0xffff888141399b30, .magic: dead4ead, .owner: krxrpcio/7001/1646, .owner_cpu: 0\nCPU: 0 UID: 0 PID: 1646 Comm: krxrpcio/7001 Not tainted 6.12.0-rc2-build3+ #4351\nHardware name: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014\nCall Trace:\n<TASK>\ndump_stack_lvl+0x47/0x70\ndo_raw_spin_lock+0x3c/0x90\nrxrpc_kernel_shutdown_call+0x83/0xb0\nafs_put_call+0xd7/0x180\nrxrpc_notify_socket+0xa0/0x190\nrxrpc_input_split_jumbo+0x198/0x1d0\nrxrpc_input_data+0x14b/0x1e0\n? rxrpc_input_call_packet+0xc2/0x1f0\nrxrpc_input_call_event+0xad/0x6b0\nrxrpc_input_packet_on_conn+0x1e1/0x210\nrxrpc_input_packet+0x3f2/0x4d0\nrxrpc_io_thread+0x243/0x410\n? __pfx_rxrpc_io_thread+0x10/0x10\nkthread+0xcf/0xe0\n? __pfx_kthread+0x10/0x10\nret_from_fork+0x24/0x40\n? __pfx_kthread+0x10/0x10\nret_from_fork_asm+0x1a/0x30\n</TASK>" ],
