CVE-2026-41156

Estado: AplazadaAlta (7.7)—

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of resources creating a write use after free scenario.

A shared resource (memory page) managed by a CPU thread of control (driver) and accessed by a GPU thread of control (Firmware) can cause a write UAF when the CPU thread frees the resource before the GPU FW has finished accessing it.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H
