CVE-2024-36405 Control-flow timing leak in Kyber reference implementation when compiled with Clang 15-18 for -Os, -O1 and other options

liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. A control-flow timing lean has been identified in the reference implementation of the Kyber key encapsulation mechanism when it is compiled with Clang 15-18 for -Os, -O1, and other...

CVE-2024-37880

The CVE affects the Kyber reference implementation prior to 9b8d306. The vulnerability is a timing side channel where poly_frommsg in poly.c can yield a vulnerable secret-dependent branch when compiled with LLVM Clang (through 18.x) with common optimizations, enabling attackers to recover an ML-K...
