https://notcve.org/view.php?id=CVE-2022-40133
A use-after-free(UAF) vulnerability was found in function 'vmw_execbuf_tie_context' in drivers/gpu/vmxgfx/vmxgfx_execbuf.c in Linux kernel's vmwgfx driver with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS). Se ha encontrado una vulnerabilidad de uso de memoria previamente liberada (UAF) en la función "vmw_execbuf_tie_context" en el archivo drivers/gpu/vmxgfx/vmxgfx_execbuf.c en el controlador vmwgfx del kernel de Linux con el archivo de dispositivo "/dev/dri/renderD128 (o Dxxx)". Este fallo permite a un atacante local con una cuenta de usuario en el sistema conseguir privilegios, causando una denegación de servicio (DoS) A use-after-free vulnerability was found in the Linux kernel's vmwgfx driver in vmw_execbuf_tie_context. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, who can issue an ioctl() on the resulting file descriptor, to crash the system, causing a denial of service. • https://bugzilla.openanolis.cn/show_bug.cgi?id=2075 https://access.redhat.com/security/cve/CVE-2022-40133 https://bugzilla.redhat.com/show_bug.cgi?id=2133453 • CWE-416: Use After Free •
