AWS VDP: V2Plugin.Decrypt panics on empty ciphertext (Remote DoS)

A vulnerability was discovered in the "aws-encryption-provider" component where the "V2Plugin.Decrypt" function accessed the ciphertext slice without checking if it was empty, leading to a panic and crashing the entire gRPC server process...

RustCrypto Has Insufficient Length Validation in decrypt() in SM2-PKE

Summary A denial-of-service vulnerability exists in the SM2 public-key encryption PKE implementation: the decrypt path performs unchecked slice::splitat operations on input buffers derived from untrusted ciphertext. An attacker can submit short/undersized ciphertext or carefully-crafted DER-encod...

CVE-2026-22700 RustCrypto Has Insufficient Length Validation in decrypt() in SM2-PKE

RustCrypto: Elliptic Curves is general purpose Elliptic Curve Cryptography ECC support, including types and traits for representing various elliptic curve forms, scalars, points, and public/secret keys composed thereof. In versions 0.14.0-pre.0 and 0.14.0-rc.0, a denial-of-service vulnerability...

SM2-PKE has Unchecked AffinePoint Decoding (unwrap) in decrypt()

Summary A denial-of-service vulnerability exists in the SM2 PKE decryption path where an invalid elliptic-curve point C1 is decoded and the resulting value is unwrapped without checking. Specifically, AffinePoint::fromencodedpoint&encodedc1 may return a None/CtOption::None when the supplied...
