When a crafted DDS file declares a D3D9 pixel format but sets a lower bits-per-pixel (bpp) value in the header, the loader allocates an undersized heap buffer. Subsequent pixel data consumption at the real format's stride causes a write past the heap buffer boundary, leading to heap metadata corruption and potential code execution.","published":"2026-08-08T16:16:49.093","modified":"2026-08-08T16:16:49.093","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-42170"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2461726"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T16:16:49.093"}}
