What is CVE-2026-16280?

An integer overflow vulnerability exists in the calculation of physical offsets for sparse PMRs within the Imagination Technologies GPU driver. This flaw may occur when dealing with PMRs exceeding 4 GB in size, resulting in 32-bit truncation of address computations. Consequently, this can lead to incorrect mappings by the GPU MMU, potentially allowing non-privileged users to access unintended physical memory, thereby risking memory corruption and information disclosure.

Affected Version(s)

Graphics DDK Linux 1.18 RTM2

Graphics DDK Linux 23.2 RTM2

Graphics DDK Linux 24.2 RTM2
