CVE-2026-7639

Software installed and run as a non-privileged user may conduct a sequence of improper GPU system calls causing use after free, which helps in facilitating unprivileged memory access from a shader code. Triggering failure path in the MMU mapping logic by a malicious code could lead to incomplete cleanup of an internal driver state, allowing for future unauthorized access to the contents of the physical memory.

Summary		(es) Software instalado y ejecutado como un usuario no privilegiado puede realizar una secuencia de llamadas al sistema de GPU impropias causando uso después de liberar, lo que ayuda a facilitar el acceso a memoria no privilegiado desde un código de sombreador. Activar una ruta de fallo en la lógica de mapeo de la MMU mediante un código malicioso podría llevar a una limpieza incompleta de un estado interno del controlador, permitiendo acceso no autorizado futuro a los contenidos de la memoria física.
