CVE-2026-16280 Details
Description
An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in memory corruption or information disclosure.
An integer overflow vulnerability has been identified in the GPU driver from Imagination Technologies, specifically in the handling of sparse Physical Memory Regions (PMRs). This vulnerability affects DDK releases up to and including 26.1 RTM1. The issue arises when calculating physical offsets for sparse PMRs larger than 4 GB, leading to a 32-bit truncation of address computations. As a result, incorrect GPU Memory Management Unit (MMU) mappings can occur, potentially allowing a non-privileged user to access unintended physical memory. This could lead to memory corruption or unauthorized information disclosure.
The DDK kernel module has been updated to correct the integer overflow vulnerability by improving the handling of address calculations, ensuring that physical addresses are accurately represented and preventing truncation. Users should upgrade to the latest DDK release to apply this fix.
