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.","score":5.5,"severity":"medium","published":"2026-09-18T14:13:53.641Z","modified":"2026-11-06T02:11:11.075Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 10","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:enterprise_linux:10"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93653"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 6","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/o:redhat:rhel_els:6"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93653"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 7","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/o:redhat:rhel_els:7"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93653"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 7","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/o:redhat:rhel_els:7"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93653"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 8","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:enterprise_linux:8"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93653"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 9","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:enterprise_linux:9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93653"},{"vendor":"Red Hat","name":"Red Hat Hardened Images","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:hummingbird:1"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93653"}],"remediation":[{"text":"To mitigate this issue, avoid opening or processing untrusted PDF files with applications that rely on Poppler's Splash backend.
