Fixed invalid pointer dereference in CMP server via crafted protectionAlg.
(CVE-2026-63076)
Fixed unbounded memory growth in QUIC server incoming channel queue.
(CVE-2026-14456)
Fixed RPK server signature algorithm selection being able to dereference
a missing certificate.
(CVE-2026-14457)
Fixed excessive memory use buffering DTLS records for a future epoch.
(CVE-2026-54874)
Fixed client-side memory leak in OCSP response checking.
(CVE-2026-54876)
