CVE-2026-45201: CWE-1284: Improper Validation of Specified Quantity in Input in Imagination Technologies Graphics DDK
Description
CVE-2026-45201 is a high-severity vulnerability in Imagination Technologies Graphics DDK where improper validation of a specified log2 page size during GPU system calls can lead to out-of-bounds (OOB) read and/or write. This occurs when software running as a non-privileged user passes an invalid log2 page size, causing 4K pages to be treated as higher order pages and enabling memory access beyond intended boundaries.

Technical Analysis
This vulnerability involves improper validation of the log2 page size parameter in GPU system calls within the Imagination Technologies Graphics DDK. When a non-privileged user supplies a crafted log2 page size value, the system may incorrectly treat 4K pages as larger pages, resulting in out-of-bounds memory reads or writes. This can lead to unauthorized memory access and potential compromise of confidentiality, integrity, and availability of the system.
Potential Impact
Successful exploitation allows a non-privileged user to perform out-of-bounds memory reads and writes beyond the 4K page boundary. This can lead to high impact on confidentiality, integrity, and availability of the affected system components.
