JSON

An integer overflow was found in the Linux kernel’s vmwgfx driver. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, and able to issue an ioctl() on the resulting file descriptor to crash the system, causing a denial of service.

Mitigation

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>.
