kernel: RDMA/mana: Validate rx_hash_key_len

A flaw was found in the Linux kernel's RDMA/mana component. A local user could exploit this vulnerability by providing an invalid rxhashkeylen value through a user-space API uAPI structure. This invalid value is then used in a memcpy operation without proper bounds checking, allowing the user to...

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...

CVE-2026-8720

wcBlake2bHmacFinal and wcBlake2sHmacFinal discard the message when the key length exceeds the block size, producing a MAC that is independent of the input. When the supplied key is longer than the BLAKE2 block size the key-hashing branch reinitialized the running hash state, discarding the...

DEBIAN-CVE-2026-6329

PKCS12 MAC verification uses an attacker-controlled comparison length, weakening the integrity check on the MAC and allowing a mismatched MAC to be accepted. The PKCS12 verify path compared the locally computed HMAC against the MAC parsed from the PKCS12 structure using a length taken directly fr...

CVE-2026-8720

CVE-2026-8720 affects wolfSSL’s HMAC-BLAKE2 APIs (wc_Blake2bHmacFinal, wc_Blake2sHmacFinal). When the supplied key length exceeds the BLAKE2 block size, the key-hashing branch reinitializes the running hash state and discards accumulated message data, causing the MAC to depend only on the key and...
