Description Ganesh 2026-07-20 14:24:04 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A vulnerability was determined in allegro up to bcf65b994ef29fb3fc2e10b660e6288723d5209e. This impacts the function AssetLastHostname.increment_hostname of the file src/ralph/assets/models/assets.py of the component Hostname Allocation Handler. Executing a manipulation of the argument counter can lead to race condition. Attacks of this nature are highly complex. The exploitability is said to be difficult. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.

Comment 1 Artur Frenszek-Iwicki 2026-07-20 14:45:25 UTC
The allegro5 Fedora Linux package contains the Allegro game programming library:
https://github.com/liballeg/allegro5

Whereas the CVE is about a bug in the "Ralph" library, maintained by Allegro, a Polish tech company:
https://github.com/allegro/ralph/issues/3950

Apart from the name clash, there is nothing linking the two projects.
Closing as NOTABUG.
