{"id":"CVE-2026-19199","state":"PUBLISHED","title":"GPU DDK - OOB write due to freelist size integer overflow in RGXCreateHWRTDataSet","description":"Software installed and run as a non-privileged user may conduct improper system calls to allocate physical memory. A 32-bit integer overflow in the KM driver during page-to-byte conversion of an allocation size can result in an undersized kernel buffer allocation. This may allow unallocated or previously allocated physical pages to be mapped into an attacker-controlled GPU MMU context, leading to disclosure of sensitive kernel data.","publishedAt":"2026-10-30T02:03:39.562Z","updatedAt":"2026-10-30T02:03:39.562Z","severity":null,"assigner":"imaginationtech","products":["Imagination Technologies Graphics DDK"],"affected":[{"vendor":"Imagination Technologies","product":"Graphics DDK","defaultStatus":"unknown","versions":[{"version":"1.18 RTM2","status":"affected","versionType":"custom"},{"version":"23.2 RTM2","status":"affected","versionType":"custom"},{"version":"24.2 RTM2","status":"affected","versionType":"custom"},{"version":"25.1 RTM2","status":"affected","lessThanOrEqual":"25.3 RTM","versionType":"custom"},{"version":"26.1 RTM2","status":"affected","versionType":"custom"},{"version":"26.2 RTM","status":"unaffected","versionType":"custom"}],"platforms":["Linux","Android"]}],"references":["https://www.imaginationtech.com/gpu-driver-vulnerabilities/"],"weaknesses":["CWE-190"],"ingestedAt":"2026-10-30T02:14:07.475Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/19xxx/CVE-2026-19199.json","commit":"4162c4bdc6173c2721f85163948714be6de1e241","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-19199","state":"PUBLISHED","datePublished":"2026-10-30T02:03:39.562Z","dateUpdated":"2026-10-30T02:03:39.562Z","assignerShortName":"imaginationtech","assignerOrgId":"367425dc-4d06-4041-9650-c2dc6aaa27ce","dateReserved":"2026-08-07T02:20:07.189Z"},"containers":{"cna":{"title":"GPU DDK - OOB write due to freelist size integer overflow in RGXCreateHWRTDataSet","descriptions":[{"lang":"en","value":"Software installed and run as a non-privileged user may conduct improper system calls to allocate physical memory.
