2) Out-of-bounds read

Risk: Low

CVSSv3: 5.2 [CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-3964

CWE-ID: CWE-125 - Out-of-bounds Read

Exploit availability: No

Description

The vulnerability allows a local attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the EHCI USB controller. A local attacker can trigger out-of-bounds read error and read contents of memory on the system.

Mitigation

Install updates from vendor's website.
