CVE-2026-53302

The CVE-2026-53302 issue is in the Linux kernel cryptographic module (EIP93 hardware accelerator). The root cause is in eip93_hmac_setkey(): it allocates a temporary ahash transform for HMAC key material using a driver name (e.g., sha256-eip93) but masks CRYPTO_ALG_ASYNC, which excludes async alg...

DEBIAN-CVE-2026-6331

HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...
