CVE-2026-64534

The CVE-2026-64534 issue affects the Linux kernel nvmet-tcp path for NVMe over TCP. A data-digest mismatch could trigger an unconditional nvmet_req_uninit() cleanup, which, if the command arrived via the nvmet_tcp_handle_req_failure() path, results in a refcount underflow and a use-after-free tha...

CVE-2026-54763

A flaw was found in Traefik, an HTTP reverse proxy and load balancer. The BasicAuth, DigestAuth, and ForwardAuth middlewares in Traefik do not correctly treat underscore-variant header names. This allows a remote attacker to inject a specially crafted header that bypasses Traefik's security...

openssl: Heap Use-After-Free in OpenSSL PKCS7_verify()

A flaw was found in OpenSSL. When processing a specially crafted PKCS7 or S/MIME Secure/Multipurpose Internet Mail Extensions signed message, a heap use-after-free vulnerability in the PKCS7verify function can be triggered. This occurs if the SignedData digestAlgorithms field is present as an emp...
