CVE-2026-68122

A flaw was found in the Linux kernel's ovpn module. A race condition in the TCP error handling paths can lead to a reference count leak. This occurs when an internal object's reference count is incremented twice but decremented only once, preventing the object from being properly released. Over...

CVE-2026-68122

CVE-2026-68122: Linux kernel ovpn code has a race in TCP error paths where ovpn_peer_hold() refs can be leaked if schedule_work() is already pending. The fix is to check schedule_work() return value on both RX/TX error paths and drop the extra reference with ovpn_peer_put() when the work is alrea...
