CVE-2025-58409 [LOW] CWE-119 CVE-2025-58409: Software installed and run as a non-privileged user may conduct improper GPU system calls to subvert Software installed and run as a non-privileged user may conduct improper GPU system calls to subvert GPU HW to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their be

CVE-2025-58408 [MEDIUM] CWE-416 CVE-2025-58408: Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger reads of stale data that can lead to kernel exceptions and write use-after-free. The Use After Free common weakness enumeration was chosen as the stale data can include handles to resources in which the reference counts can become unbalanced. This c

CVE-2025-58410 [HIGH] CWE-280 CVE-2025-58410: Software installed and run as a non-privileged user may conduct improper GPU system calls to gain wr Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permissions to memory buffers exported as read-only. This is caused by improper handling of the memory protections for the buffer resource.
