On certain platforms, when the compiler process has system privileges this could enable further exploits on the device.\n\n\n\nAn edge case using a very large value in switch statements in GPU shader code can cause a segmentation fault in the GPU shader compiler due to an out-of-bounds write access.","published":"2026-03-20T23:16:42.000Z","lastModified":"2026-06-17T10:18:59.000Z","status":"Analyzed","sourceIdentifier":"367425dc-4d06-4041-9650-c2dc6aaa27ce","cvss":{"version":"3.1","score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},"cwe":["CWE-823","CWE-787"],"affected":["imaginationtech/ddk"],"epss":{"score":0.00299,"percentile":0.22405,"date":"2026-10-26","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 (0.30%).
