Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

Botan 3.6.0

  1. Upgrade Botan library to version 3.6.0 or later
  2. Verify the upgrade by checking the installed Botan version (e.g., using botan --version or your application's library version check)
  3. If using a package manager (e.g., apt, yum, brew, conan), update to the latest available package that includes version 3.6.0 or newer
  4. Rebuild any applications that statically link against Botan to ensure they use the updated library
  5. Review any custom GHASH or AES-GCM implementations to ensure they now use the fixed code path
Caveat Minor: This is a security patch release; GHASH computational behavior should remain compatible, but verify cryptographic output in any custom integrations

Generated from the published advisory — verify against the referenced sources before acting.

We can perform the upgrade in your staging environment and verify nothing breaks — typical engagement from $1,600. Get the upgrade done
