SUSE CVE-2026-53131

In the Linux kernel, the following vulnerability has been resolved: netfilter: require Ethernet MAC header before using ethhdr ip6teui64, xtmac, the bitmap:ip,mac, hash:ip,mac, and hash:mac ipset types, and nflogsyslog access ethhdrskb after either assuming that the skb is associated with an...

SUSE CVE-2026-53230

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix slab-out-of-bounds in mlx5querynicvportmaclist mlx5querynicvportmaclist sizes its firmware command buffer using the PF's logmaxcurrentuc/mclist capabilities. When querying a VF vport with a larger configured max via...

EUVD-2026-39565

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...

When HAVEENCRYPTTHENMAC is configured, the implementation could fall back to MAC-then-Encrypt rather than enforcing Encrypt-then-MAC...

EUVD-2026-39579

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...

CVE-2026-53131

A flaw was found in the Linux kernel's netfilter component. Certain netfilter modules, including ip6teui64 and xtmac, accessed Ethernet MAC header data without first verifying that an Ethernet device was associated with the network packet or that the MAC header was present and of sufficient lengt...

CVE-2026-53230

A flaw was found in the Linux kernel's mlx5 driver. The mlx5querynicvportmaclist function, which handles querying network interface card NIC virtual port vport MAC addresses, incorrectly sizes its internal buffer. When a Virtual Function VF vport is queried with a larger configured maximum, the...

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...
