Details

It was discovered that the NVIDIA GPU display driver for the Linux kernel
contained a vulnerability that allowed user-mode clients to access legacy
privileged APIs. A local attacker could use this to cause a denial of
service or escalate privileges. (CVE-2021-1052)

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.
(CVE-2021-1053)

Xinyuan Lyu discovered that the NVIDIA GPU display driver for the Linux
kernel did not properly restrict device-level GPU isolation. A local
attacker could use this to cause a denial of service or possibly expose
sensitive information. (CVE-2021-1056)
