UBUNTU-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-2026-6330

The ML-KEM ARM64 NEON ciphertext comparison only compares half of the input, breaking the Fujisaki-Okamoto transform's implicit rejection and weakening IND-CCA2 security on that code path. The constant-time comparison effectively ignored part of the re-encrypted ciphertext, so a decapsulating par...

CVE-2026-10097

wolfSSL's AVX2-optimized ML-KEM implementation mlkemcmpavx2 compares only 1536 of the 1568 ciphertext bytes during the Fujisaki-Okamoto re-encryption check in ML-KEM-1024 decapsulation. Ciphertexts that differ from the expected re-encryption solely in bytes 1536-1567 bypass implicit rejection and...

EUVD-2026-39553

ML-KEM-1024 x64 AVX2 implicit rejection failure in the Fujisaki-Okamoto transform breaks IND-CCA2 security, allowing decapsulation to deviate from the implicit-rejection behavior required by the standard. The AVX2 constant-time ciphertext comparison used during decapsulation never compared the...

CVE-2026-10097 ML-KEM-1024 x64 AVX2 incomplete cipher text comparison enables IND-CCA2 break and static private-key recovery

wolfSSL's AVX2-optimized ML-KEM implementation mlkemcmpavx2 compares only 1536 of the 1568 ciphertext bytes during the Fujisaki-Okamoto re-encryption check in ML-KEM-1024 decapsulation.

CVE-2026-47770 jq: stack overflow in deep structural equality

jq is a command-line JSON processor. Prior to 1.8.2, comparing two sufficiently deeply nested arrays with the == operator exhausts the C stack on jq's ordinary command-line surface, resulting in denial of service via stack exhaustion uncontrolled recursion. The crash occurs in jq's recursive...

CVE-2026-9800 Keycloak-policy-enforcer: keycloak policy enforcer: authorization bypass via incorrect uri comparison

A flaw was found in Keycloak Policy Enforcer. This vulnerability allows any authenticated user to bypass all authorization policies, including role, scope, and User-Managed Access UMA permission checks. By including the configured access-denied page path within a request URL, either as a path...

jq: jq: Denial of Service via deeply nested array comparison

A flaw was found in jq, a command-line JSON processor. This vulnerability allows a local user or an attacker providing malicious input to cause a denial of service DoS by comparing two sufficiently deeply nested arrays using the '==' operator. This action exhausts the C stack due to uncontrolled...

PT-2026-52603

Name of the Vulnerable Software and Affected Versions ML-KEM affected versions not specified Description An issue exists in the ARM64 NEON ciphertext comparison where only half of the input is compared. This failure breaks the implicit rejection of the Fujisaki-Okamoto transform—a method used to...
