CVE-2016-8400
NVIDIA Tegra kernel driver contains a vulnerability in the NVIDIA Tegra library (libnvrm), where there is the potential to read or write a buffer using an index or pointer that references a memory location after the end of the buffer, which may lead to a denial of service or possible escalation of privileges.
CVSS Base Score 7.1
CVSS Temporal Score 6.4
CVSS Vector CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H/E:P/RL:O/RC:C
CVE-2017-0429
NVIDIA Tegra kernel driver contains a vulnerability in NVHOST, where an attacker has the ability to write an arbitrary value to an arbitrary location, which may lead to an escalation of privileges.
CVSS Base Score: 7.1
CVSS Temporal Score: 6.4
CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N/E:P/RL:O/RC:C
