Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in the processPacket method of KCCMBlockCipher, which invokes processAAD only when associated data is present, so with no AAD the G1 block nonce, length, flag is never mixed into the MAC and...

UBUNTU-CVE-2026-13758

CryptX versions before 0.088001 for Perl compare AEAD authentication tags in non-constant time in the streaming decryptdone path. The decryptdone$tag form compares it against the computed tag with memNE memcmp != 0, which short-circuits on the first differing byte, so its run time depends on the...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to an integer overflow in the wcCmacUpdate function. An attacker can generate forged CMAC tags by exploiting the wraparound of the totalSz variable after processing 4 GiB of data, which causes the...

CVE-2026-3337 Timing Side-Channel in AES-CCM Tag Verification in AWS-LC

Observable timing discrepancy in AES-CCM decryption in AWS-LC allows an unauthenticated user to potentially determine authentication tag validity via timing analysis. The impacted implementations are through the EVP CIPHER API: EVPaes128ccm, EVPaes192ccm, and EVPaes256ccm. Customers of AWS servic...
