In the Linux kernel, the following vulnerability has been resolved:
netfilter: nfnetlink_queue: acquire rcu_read_lock() in instance_destroy_rcu()
syzbot reported that nf_reinject() could be called without rcu_read_lock() :
WARNING: suspicious RCU usage
6.9.0-rc7-syzkaller-02060-g5c1672705a1a #0 Not tainted
net/netfilter/nfnetlink_queue.c:263 suspicious rcu_dereference_check() usage!
other info that might help us debug this:
rcu_scheduler_active = 2, debug_locks = 1
2 locks held by syz-executor.4/13427:
