CISA-ADP AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N

CISA-ADP CWE-203

Botan before 3.6.0, when certain LLVM versions are used, has compiler-induced secret-dependent control flow in lib/utils/ghash/ghash.cpp in GHASH in AES-GCM. There is a branch instead of an XOR with carry. This was observed for Clang in LLVM 15 on RISC-V.
