CVE-2026-112922

Ghostscript: out-of-bounds read in ghostscript shade_next_color via integer overflow of indexed color index in mesh shading

Published Oct 30, 2026 CVSS 3.1 · 3.3 Low EPSS < 1% KEV · Not listed
Description
A flaw was found in Ghostscript. A remote attacker could exploit this vulnerability by enticing a user to process a specially crafted PDF or PostScript document containing malicious mesh shading data. Due to improper bounds validation during the processing of indexed color values, Ghostscript triggers an out-of-bounds memory read. Successful exploitation can lead to a Denial of Service (DoS) through an application crash or result in limited information disclosure.
