Kernel heap corruption via virtual-index out-of-bounds write
Published Jun 8, 2026 · Updated Jun 8, 2026
Heap-based buffer overflow in Imagination Technologies Graphics DDK 24.2 RTM2 through 26.1 RTM1 allows local users to corrupt kernel memory. DevmemIntComputeVirtualIndicesFromLogical computes virtual indices from attacker-selected resource types and interface parameters, then writes past a kernel heap allocation. Non-privileged access to the affected Linux or Android GPU driver interface is required, and the documented consequence is kernel-memory corruption.

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=24.2 RTM
- Affected versionversion=25.1 RTM <=25.3 RTM
- Affected versionversion=26.1 RTM
