Linux kernel i810 DMA lock denial of service
| linux-i810-dma-dos (15972) |  Medium Risk |
Description:
Linux kernel is vulnerable to a denial of service. The i810 Direct Rendering Manager (DRM) driver fails to properly check the DMA lock. A local or remote authenticated attacker could send arbitrary values to the video card to cause the X server to crash or possibly modify video output
