Description

This security bulletin contains information about 1 vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-9443)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local privileged user to execute arbitrary code.

In the Android kernel in the vl53L0 driver there is a possible out of bounds write due to a permissions bypass. This could lead to local escalation of privilege due to a set_fs() call without restoring the previous limit with System execution privileges needed. User interaction is not needed for exploitation.
