Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-41079)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to out-of-bounds read in the CUPS SNMP backend when processing crafted SNMP responses during supply-level polling. A remote attacker can send a specially crafted SNMP response to disclose sensitive information.

The leaked memory is converted from UTF-16 to UTF-8 and becomes visible to authenticated users via IPP Get-Printer-Attributes responses and the CUPS web interface. Exploitation requires an SNMP-discovered printer on the same LAN segment.
