Description Jon Moroney 2026-04-07 18:31:17 UTC

Comment 1 Peter Lemenkov 2026-04-07 18:52:35 UTC 
CVE-2026-32144 (OCSP designated-responder authorization bypass in public_key) only affects Erlang/OTP ≥ 27.0, as confirmed by the upstream security advisory: https://github.com/erlang/otp/security/advisories/GHSA-gxrm-pf64-99xm

Red Hat and the Fedora community have switched Erlang packaging for EPEL to the CentOS Messaging SIG (installable via `dnf install centos-release-messaging`). The CentOS Messaging SIG ships Erlang 26.x only, which is explicitly listed as unaffected by this CVE. Closing as NOTABUG.
