Comment 1 Peter Lemenkov 2026-07-10 17:41:34 UTC
This is delivered for EL9/EL10 via the CentOS Messaging SIG rather than EPEL. Backported erlang builds addressing this CVE are being prepared for c9s and c10s (Messaging SIG); users can obtain them with `dnf install centos-release-messaging` (works on CentOS Stream, RHEL, AlmaLinux, and Rocky). The builds are working their way through the SIG testing tag and will reach stable soon enough. Will update once that lands.

Comment 2 Peter Lemenkov 2026-07-24 18:32:29 UTC
Current Erlang builds for EL9 and EL10 are available from the CentOS Messaging SIG, which tracks upstream releases and carries security backports. The current build is erlang-26.2.5.21-4, which addresses this issue.

These packages work on RHEL, CentOS Stream, AlmaLinux, Rocky Linux and other RHEL-compatible distributions:

    dnf install centos-release-messaging
    dnf install erlang

Closing here, as Erlang updates for EL9 and EL10 are delivered through the Messaging SIG. Please reopen if the SIG builds don't cover your case.
