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...

CVE-2026-46344

CVE-2026-46344 pertains to the liboqs C library (post-quantum cryptography). Before v0.16.0, there is a heap/out-of-bounds risk in XMSS/XMSS^MT stateful signature verification when a public key’s OID points to a larger parameter set than the declared algorithm, causing xmss_sign_open / xmssmt_sig...
