Memory corruption via overflowed sparse-map size
Published Jun 12, 2026 · Updated Jun 12, 2026
Out-of-bounds write in Graphics DDK through 26.1 RTM1 allows remote attackers to corrupt GPU-process memory via crafted WebGPU content. The CalculateNPOTTwiddleSparsePageMap3D routine derives a sparse-page-map allocation size from untrusted dimensions without preventing integer overflow, then writes beyond the undersized buffer. A web page must reach the GPU GLES render process; the vendor documents memory corruption and browser or GPU-process crashes, not code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.18 RTM
- Affected versionversion=23.2 RTM
- Affected versionversion=24.2 RTM
- Affected versionversion=25.1 RTM <=25.3 RTM
