CVE-2025-68276 (GCVE-0-2025-68276)

Vulnerability from cvelistv5 – Published: 2026-01-12 17:31 – Updated: 2026-01-12 18:41

Title

Avahi has a reachable assertion in avahi_wide_area_scan_cache

Summary

Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In 0.9-rc2 and earlier, an unprivileged local users can crash avahi-daemon (with wide-area disabled) by creating record browsers with the AVAHI_LOOKUP_USE_WIDE_AREA flag set via D-Bus. This can be done by either calling the RecordBrowserNew method directly or creating hostname/address/service resolvers/browsers that create those browsers internally themselves.

Severity

5.5 (Medium)
