CVE-2026-93653

A denial of service flaw was found in Poppler's Splash backend. A crafted PDF with tiling-pattern geometry approaching the int32 boundary can cause SplashOutputDev::tilingPatternFill to compute an attacker-controlled repeat count that drives an excessively long loop in the pattern-fill scanline routine, without a corresponding memory allocation. An attacker could exploit this by supplying a malicious PDF to an application that renders it via Poppler's Splash backend, causing the rendering process to consume 100% CPU for an attacker-controlled, extended duration.
