In the Linux kernel, the following vulnerability has been resolved: tipc: Fix use-after-free in tipc_mon_reinit_self(). syzbot reported use-after-free of tipc_net(net)->monitors[] in tipc_mon_reinit_self(). [0] The array is protected by RTNL, but tipc_mon_reinit_self() iterates over it without RTNL. tipc_mon_reinit_self() is called from tipc_net_finalize(), which is always under RTNL except for tipc_net_finalize_work(). Let's hold RTNL in tipc_net_finalize_work().

An update of the linux package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tipc: Fix use-after-free in tipc_mon_reinit_self(). syzbot reported use-after-free of     tipc_net(net)->monitors[] in tipc_mon_reinit_self(). [0] The array is protected by RTNL, but     tipc_mon_reinit_self() iterates over it without RTNL. tipc_mon_reinit_self() is called from     tipc_net_finalize(), which is always under RTNL except for tipc_net_finalize_work().
