Description Thibault Guittet 2026-08-11 07:42:45 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 EchoLink implementation. An out-of-bounds read in the RTCP/SDES packet handling allows a pre-auth remote attacker to read beyond buffer boundaries via crafted UDP packets, potentially leading to information disclosure or a crash. 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.
