CVE-2026-81688

opensslencrypt versions before 1.4.9 store an unkeyed SHA-256 hash of the plaintext in the cleartext file header metadata. Attackers can read this hash without the password to confirm guessed plaintexts offline or fingerprint identical plaintexts across separately-encrypted files...

CVE-2026-59808 AVideo Authentication Bypass via Unkeyed Video Hash Disclosure

AVideo through commit 9c39d8c8 contains an authentication bypass vulnerability where deduplicateByEncoderQueueId returns videoidhash credentials for any video by encoderqueueid without ownership verification, and useVideoHashOrLogin converts this hash into passwordless login as the video owner...

SUSE CVE-2017-17806

The HMAC implementation crypto/hmac.c in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AFALG-based hash interface CONFIGCRYPTOUSERAPIHASH and the SHA-3 hash algorithm CONFIGCRYPTOSHA3 to caus...

kernel: HMAC implementation does not validate that the underlying cryptographic hash algorithm is unkeyed allowing local attackers to cause denial-of-service

The HMAC implementation crypto/hmac.c in the Linux kernel, before 4.14.8, does not validate that the underlying cryptographic hash algorithm is unkeyed. This allows a local attacker, able to use the AFALG-based hash interface CONFIGCRYPTOUSERAPIHASH and the SHA-3 hash algorithm CONFIGCRYPTOSHA3, ...
