Описание
A use-after-free(UAF) vulnerability was found in function 'vmw_cmd_res_check' 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).
A use-after-free vulnerability was found in the Linux kernel's vmwgfx driver in vmw_cmd_res_check. 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.
Отчет
Systems making use of the vmwgfx driver are potentially affected by this flaw; systems without the vmwgfx driver loaded are not affected by this flaw.
Меры по смягчению последствий
To mitigate this issue, it is possible to prevent the affected code from being loaded by blacklisting the vmwgfx kernel module. For instructions relating to blacklisting a kernel module, please see https://access.redhat.com/solutions/41278.
