In the Linux kernel, the following vulnerability has been resolved: skmsg: pass gfp argument to alloc_sk_msg() syzbot found that alloc_sk_msg() could be called from a non sleepable context. sk_psock_verdict_recv() uses rcu_read_lock() protection. We need the callers to pass a gfp_t argument to avoid issues. syzbot report was: BUG: sleeping function called from invalid context at include/linux/sched/mm.h:274 in_atomic(): 0, irqs_disabled(): 0, non_block: 0, pid: 3613, name: syz-executor414 preempt_count: 0, expected: 0 RCU nest depth: 1, expected: 0 INFO: lockdep is turned off.
