Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-87875)

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

CVSSv4: 5.3 [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]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to an out-of-bounds read caused by a missing source-length bound in cupsUTF32ToUTF8() in cups/transcode.c when converting SNMP supply descriptions reported as UCS-4 or UTF-32 during printer supply-level polling. A remote attacker can send specially crafted SNMP responses from a malicious or compromised printer on the local network to disclose sensitive information.

On LP64 platforms, cups_utf32_t is an 8-byte unsigned long, widening the possible overread because each low-codepoint word consumes eight source bytes but only one byte of the output budget.
