Description Thibault Guittet 2026-08-11 07:37:03 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 flaw was found in svxlink's remotetrx NetUplink component. When a server initiates a disconnect, the connection object is leaked rather than properly freed. A remote attacker can repeatedly trigger disconnects to cause unbounded memory growth, leading to a denial of service. Fixed in version 26.05.1.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
