Published: 7 January 2021
NVIDIA GPU Display Driver for Windows and Linux, all versions, contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape or IOCTL in which improper validation of a user pointer may lead to denial of service.
From the Ubuntu Security Team
It was discovered that the NVIDIA GPU display driver for the Linux kernel did not properly validate a pointer received from userspace in some situations. A local attacker could use this to cause a denial of service.
