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":"2026-08-08T16:16:49.000Z","lastModified":"2026-09-01T14:25:13.000Z","status":"Analyzed","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","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"},"cwe":["CWE-131"],"affected":["redhat/enterprise linux"],"epss":{"score":0.00192,"percentile":0.08748,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.19%).
