CVE-2026-46344

A flaw was found in liboqs, a C-language cryptographic library. An out-of-bounds read vulnerability exists in the XMSS and XMSS^MT stateful signature verification code. A remote attacker could exploit this by providing a specially crafted public key that causes the verification function to read...

CVE-2026-44518

liboqs (C library for post-quantum crypto) exposes a buffer overread in XMSS/XMSS^MT stateful signature verification prior to 0.16.0. If verify is called with a signature shorter than the parameter’s sig_bytes, length isn't validated and the code reads past the end of the signature buffer. The ex...
