Description OSIDB Bzimport 2026-08-11 07:31:31 UTC 
A flaw was found in svxlink's RtlTcp component. A malformed rtl_tcp greeting from a remote source triggers an exit(1) call, causing the entire svxlink daemon to terminate. A remote attacker can exploit this to achieve a full denial of service of the svxlink repeater controller. Fixed in version 26.05.1.
