CVE-2026-41079: CWE-125: Out-of-bounds Read in OpenPrinting cups
CVE-2026-41079 is an out-of-bounds read vulnerability in OpenPrinting CUPS versions prior to 2. 4. 17. A network-adjacent attacker can send a crafted SNMP response to the CUPS SNMP backend, causing it to read up to 176 bytes beyond a stack buffer. The leaked memory is converted from UTF-16 to UTF-8 and exposed as printer supply description strings, which authenticated users can view via IPP Get-Printer-Attributes responses and the CUPS web interface. This vulnerability has a medium severity with a CVSS score of 4. 3 and does not impact integrity or availability. The issue is fixed in version 2. 4. 17.
AI Analysis
Technical Summary
OpenPrinting CUPS before version 2.4.17 contains a CWE-125 out-of-bounds read vulnerability in its SNMP backend. When processing SNMP responses, a crafted response can cause the system to read up to 176 bytes beyond the intended stack buffer. The leaked data is then converted from UTF-16 to UTF-8 and stored as printer supply description strings. These strings are accessible to authenticated users through IPP Get-Printer-Attributes responses and the CUPS web interface, potentially exposing sensitive memory contents. The vulnerability does not affect integrity or availability and requires network adjacency but no privileges or user interaction. The vulnerability is addressed in CUPS version 2.4.17.
Potential Impact
The vulnerability allows a network-adjacent attacker to cause an out-of-bounds read, leaking up to 176 bytes of memory past a stack buffer. The leaked data is exposed as printer supply description strings visible to authenticated users. This results in limited confidentiality impact (information disclosure) without affecting system integrity or availability. There are no known exploits in the wild.
Mitigation Recommendations
This vulnerability is fixed in OpenPrinting CUPS version 2.4.17. Users should upgrade to version 2.4.17 or later to remediate this issue. Since no official patch link or advisory is provided, verify the upgrade availability from the OpenPrinting project. No additional mitigations are indicated.
