CVE-2026-99059In the Linux kernel, the following vulnerability has been resolved: wireguard: noise: reject response consumption after intermediate initiation Two threads begin processing... Executive summary A race condition in the Linux kernel's WireGuard VPN code could, in theory, let a second handshake session be derived from the same state after a concurrent handshake initiation. The advisory describes this as very unlikely to be hit in practice, and the fix adds a check to prevent it. Technical summary The flaw is a race condition (time-of-check to time-of-use) in the WireGuard noise handshake code, where a handshake response can be consumed after an intermediate handshake initiation has reset the state. The attack vector and preconditions beyond concurrent processing of a duplicated response message are not stated. The fix compares the ephemeral private key on the stack with the peer's latest handshake state before accepting the response. Affected kernel versions and fixed versions are not stated, and no workaround is described. No CVSS score, exploitation status, or detection guidance is stated. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
