Memory Buffer Vulnerability in GPU Drivers by Imagination Technologies

CVE-2026-65586

What is CVE-2026-65586?

This vulnerability allows a non-privileged user to exploit improper memory management within GPU drivers. Specifically, the issue arises when a memory buffer managed by a CPU thread is freed while still in use by a GPU thread. Malicious software can replace this buffer with another allocation, leading to arbitrary memory reads or writes. This security flaw poses significant risks as it allows unauthorized access to physical memory pages, compromising system integrity and confidentiality.
