CVE-2026-45918

CVE-2026-45918 concerns a race condition in the Linux kernel related to OpenVPN TCP handling. When a peer is kept alive and later removed, the kernel temporarily places the peer in a release list and detaches from the socket by restoring its proto and socket callbacks. If userspace closes the soc...
