CVE-2026-87733

An issue was discovered in the mirage-crypto-ec function before 2.2.0 for OCaml. The ECDSA functions P256,P384,P521.Dsa.pubofoctets accept 0x00, the encoding of the point at infinity, as a public key. With that public key, signatures can be forged without a private key...

CVE-2026-87732

An issue was discovered in the mirage-crypto package before 2.2.0 for OCaml. The AES.GCM.authenticatedecryptinto and Chacha20.authenticatedecryptinto functions write the decrypted plaintext into a caller-provided buffer and only then compares the tag. On a forged tag, the functions returns false,...
