Overview

CVE-2026-107886 is a low-severity vulnerability affecting openprinting cups. It was published on October 9, 2026 and has a CVSS 3.1 base score of 2.3 (LOW).

This vulnerability has a CVSS 3.1 base score of 2.3, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

OpenPrinting CUPS before 2.4.20 contains a double-free in printer-class management. When CUPS-Add-Modify-Class replaces an existing class member list, add_class() frees pclass->printers without clearing the pointer. If subsequent validation fails, the class retains the dangling pointer; CUPS-Delete-Class subsequently frees the same allocation in cupsdDeletePrinter(). A client authorized to modify and delete classes can cause scheduler-wide denial of service. The default policy requires @SYSTEM privileges.

Remediation

Check the references section for vendor advisories and patches from openprinting. Update cups to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
