CVE-2026-8720

CVE-2026-8720 affects wolfSSL’s HMAC-BLAKE2 APIs (wc_Blake2bHmacFinal, wc_Blake2sHmacFinal). When the supplied key length exceeds the BLAKE2 block size, the key-hashing branch reinitializes the running hash state and discards accumulated message data, causing the MAC to depend only on the key and...

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

Summary: CVE-2026-10097 affects wolfSSL’s ML-KEM-1024 x64 AVX2 implementation. The Fujisaki-Okamoto decapsulation path performs an incomplete ciphertext check, failing to compare the final portion of the 1568-byte ciphertext. As a result, ciphertexts manipulated in those final bytes can bypass im...

CVE-2026-53041

A flaw was found in the Linux kernel's Oracle Cluster File System version 2 OCFS2. When an OCFS2 inode has both inline and and block-based extended attributes xattrs, the listxattr function can return a size larger than the caller's buffer. This incorrect size handling can lead to a kernel bug an...

EUVD-2026-39482

Bleichenbacher padding oracle in PKCS7 KTRI decryption. When decrypting PKCS7 EnvelopedData using RSA PKCS1 v1.5 key transport, wolfSSL returned distinguishable error codes depending on whether RSA padding validation failed versus whether the decrypted content was malformed. An attacker able to...

CVE-2026-12844

CVE-2026-12844 affects List::SomeUtils::XS before 0.59 for Perl. The vulnerability is a heap buffer overflow in pairwise(), where the heap buffer is grown by a single quadrupling (alloc <

CVE-2026-12844

List::SomeUtils::XS versions before 0.59 for Perl have a heap buffer overflow in the pairwise function. pairwise collects the values returned by the block into a heap buffer sized to the longer input array, then grows the buffer before each copy with a single quadrupling alloc = 2 instead of a...

CVE-2026-40011
