Vulnerability description
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an error in the vmwgfx driver in Linux kernel. A local unprivileged user can gain access to files opened by other processes on the system through a dangling 'file' pointer.
Exploiting this vulnerability requires an attacker to have access to either /dev/dri/card0 or /dev/dri/rendererD128 and be able to issue an ioctl() on the resulting file descriptor.
Remediation
