CVE-2025-40280: tipc: Fix use-after-free in tipc_mon_reinit_self().

Published Dec 6, 2025

Updated

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

tipc: Fix use-after-free in tipcmonreinitself().

syzbot reported use-after-free of tipcnet(net)->monitors[] in tipcmonreinitself(). [0]

The array is protected by RTNL, but tipcmonreinitself() iterates over it without RTNL.

tipcmonreinitself() is called from tipcnetfinalize(), which is always under RTNL except for tipcnetfinalizework().

Let's hold RTNL in tipcnetfinalizework().
