In the Linux kernel, the following vulnerability has been resolved:

netrom: fix possible dead-lock in nrrtioctl()

syzbot loves netrom, and found a possible deadlock in nrrtioctl [1]

Make sure we always acquire nrnodelistlock before nrnodelock(nrnode)

[1] WARNING: possible circular locking dependency detected

6.9.0-rc7-syzkaller-02147-g654de42f3fc6 #0 Not tainted

syz-executor350/5129 is trying to acquire lock: ffff8880186e2070 (&nrnode->nodelock){+...}-{2:2}, at: spinlockbh include/linux/spinlock.h:356 [inline] ffff8880186e2070 (&nrnode->nodelock){+...}-{2:2}, at: nrnodelock include/net/netrom.h:152 [inline] ffff8880186e2070 (&nrnode->nodelock){+...}-{2:2}, at: nrdecobs net/netrom/nrroute.c:464 [inline] ffff8880186e2070 (&nrnode->nodelock){+...}-{2:2}, at: nrrtioctl+0x1bb/0x1090 net/netrom/nrroute.c:697

but task is already holding lock: ffffffff8f7053b8 (nrnodelistlock){+...}-{2:2}, at: spinlockbh include/linux/spinlock.h:356 [inline] ffffffff8f7053b8 (nrnodelistlock){+...}-{2:2}, at: nrdecobs net/netrom/nrroute.c:462 [inline] ffffffff8f7053b8 (nrnodelistlock){+...}-{2:2}, at: nrrtioctl+0x10a/0x1090 net/netrom/nr_route.c:697

which lock already depends on the new lock.

the existing dependency chain (in reverse order) is:
