CVE-2026-87875 (GCVE-0-2026-87875)

Vulnerability from cvelistv5 – Published: 2026-09-09 16:06 – Updated: 2026-09-10 10:38

Title

Cups: openprinting cups: heap out-of-bounds read in cupsutf32toutf8() via missing source-length bound

Summary

The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content.

Severity

4.3 (Medium)
