REWTERZ THREAT ADVISORY – CVE-2018-19788 – LINUX POLICYKIT Command Execution Vulnerability
December 10, 2018
A vulnerability has been reported in Linux Kernel, which can be exploited by malicious, local users to potentially gain escalated privileges.
IMPACT: NORMAL
PUBLISH DATE: 06-DEC-2018
OVERVIEW
An integer overflow error related to the “wmi_set_ie()” function (drivers/net/wireless/ath/wil6210/wmi.c) can be exploited to cause a buffer overflow.
ANALYSIS
In the function wmi_set_ie(), the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the ‘ie_len’ argument can cause a buffer overflow in all Android releases from CAF (Android for MSM, Firefox OS for MSM, QRD Android) using the Linux Kernel.
The vulnerability is reported in versions 4.14.x prior to 4.14.86, 4.9.135, 4.4.162, and 3.16.60. Other versions may also be affected.
AFFECTED PRODUCTS
