CVE-2026-64611 (opens in a new tab)How to fix?
A fix was pushed into the master branch but not yet published.
Overview
Affected versions of this package are vulnerable to Infinite loop in the cfIEEE1284NormalizeMakeModel function. An attacker can cause sustained CPU consumption by sending a specially crafted IEEE-1284 device ID with an empty model field over the network. This is only exploitable if the cups-browsed service is enabled.
Workaround
This vulnerability can be mitigated by stopping the cups-browsed service or restricting untrusted networks from accessing the daemon.
