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:
