CVE-2026-63925 macsec: fix replay protection at XPN lower-PN wrap

In the Linux kernel, the following vulnerability has been resolved: macsec: fix replay protection at XPN lower-PN wrap In macsecpostdecrypt, when pn is U32MAX, pn + 1 overflows u32 to 0 and the first branch never fires. If nextpnhalves.lower is also in the upper half, pnsamehalfpn, lower is true...

CVE-2026-63925

The CVE-2026-63925 issue affects the Linux kernel macsec XPN replay protection logic. When pn equals U32_MAX, pn+1 overflows to 0 and the code path for updating next_pn_halves may not fire, allowing an attacker to replay a frame carrying pn == 0xFFFFFFFF on an XPN association. The fix extends the...

GHSA-C7JM-38GQ-H67H http4k: `ServerFilters.DigestAuth` / `DigestAuthProvider` defaulted to an always-true nonce verifier, disabling replay protection in default deployments

Impact ServerFilters.DigestAuth and the underlying DigestAuthProvider both defaulted their nonceVerifier parameter to true — i.e. every nonce was accepted regardless of value, age, or prior use. Any deployment using the default configuration had no replay protection on Digest authentication; a...
