CVE-2026-42791 affects OTP 27.0 and later only (the vulnerable OCSP responder-validation path in pubkey_ocsp; fixed upstream in OTP 27.3.4.12). Status across Fedora branches: - rawhide (f45): fixed in erlang-27.3.4.14-1.fc45 - f44 / f43: not affected -- both ship OTP 26.x, which predates the affected code Closing. |
