CVE-2026-65586 Details
Description
Software installed and run as a non-privileged user may conduct improper GPU system calls to free memory in still in use, replace with another allocation and cause arbitrary memory reads or writes to physical memory pages. A memory buffer managed by a CPU thread of control (driver) and accessed by a GPU thread of control (firmware) can be freed while in use. Software installed and run as a non-privileged user may replace that buffer with another and replace a shared resource (memory page address list) managed by the CPU thread of control (driver) leading to the GPU accessing memory not managed by the CPU thread of control (driver).
A vulnerability exists in Imagination Technologies GPU drivers that allows software running as a non-privileged user to make improper GPU system calls. These calls can manipulate memory management by freeing buffers still in use, leading to a use-after-free condition. This exploitation can be used to read from or write to arbitrary physical memory pages, potentially corrupting kernel or driver memory and altering system behavior.
Users can update to the latest version of the Imagination Technologies GPU driver, which addresses this vulnerability by correcting the memory management flaws that allow for arbitrary memory access.
