Technical details
An integer overflow vulnerability exists in the Imagination Technologies Graphics DDK when calculating physical offsets for sparse Physical Memory Resources (PMRs). When handling PMRs larger than 4 GB, the address computation may undergo 32-bit truncation, resulting in incorrect GPU Memory Management Unit (MMU) mappings. A non-privileged local user can exploit this flaw to trigger access to unintended physical memory. This can result in memory corruption or the disclosure of sensitive information from other processes or the kernel. The issue is fixed in version 26.1 RTM2.
