In the Linux kernel, the following vulnerability has been resolved: tipc: fix use-after-free of the discoverer in tipc_disc_rcv() bearer_disable()… (CVE-2026-64543)CVE-2026-64543 0 A use-after-free vulnerability in the Linux kernel's TIPC (Transparent Inter-Process Communication) UDP bearer was resolved. The issue occurs because the discoverer object is freed without proper synchronization, leading to a use-after-free condition in tipc_disc_rcv() during UDP packet processing. This vulnerability is reachable from an unprivileged user namespace when TIPC and UDP media support are enabled. The fix involves freeing the discoverer object using an RCU callback and ensuring all callbacks complete before module unload.
