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...

GHSA-2X3R-HWV5-P32X Deno's AES GCM authentication tags are not verified

Summary This affects AES-256-GCM and AES-128-GCM in Deno, introduced by commit 0d1beed. Specifically, the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno...

CVE-2023-26084

The armv8decaesgcmfull API of Arm AArch64cryptolib before 86065c6 fails to the verify the authentication tag of AES-GCM protected data, leading to a man-in-the-middle attack. This occurs because of an improperly initialized variable...

GHSA-R38M-44FW-H886 AEADs/ascon-aead: Plaintext exposed in decrypt_in_place_detached even on tag verification failure

Summary In decryptinplacedetached, the decrypted ciphertext which is the correct ciphertext is exposed even if the tag is incorrect. Details This is because in decryptinplace in asconcore.rs, tag verification causes an error to be returned with the plaintext contents still in buffer. The root cau...
