About this tag
The rtnl lock tag on WindowsForum.com covers discussions about the RTNL (networking) lock in the Linux kernel, particularly in the context of security vulnerabilities and fixes. Recent content includes a thread on CVE-2025-40280, a use-after-free bug in the TIPC subsystem that occurred because the tipc_mon_reinit_self function iterated the per-net monitor array without holding the RTNL lock.
