What is CVE-2025-58364?

The OpenPrinting CUPS is an open-source printing system that can be exploited due to unsafe deserialization and validation of printer attributes in versions 2.4.12 and earlier. This vulnerability can lead to null dereference in the libcups library, causing the cups and cups-browsed services to crash on all machines in a local network that are configured to listen for printers. If the system’s firewall does not block incoming communications to the IPP port and is exposed to the public internet, an attacker can exploit this vulnerability remotely. Affected users are encouraged to upgrade to version 2.4.13 where the vulnerabilities have been addressed.

Affected Version(s)

cups < 2.4.13
