SB2018072610 - Multiple privilege escalation vulnerabilities in Intel Smart Sound Technology

Description

This security bulletin contains information about 3 vulnerabilities.

1) Memory corruption (CVE-ID: CVE-2018-3666)

CWE-ID: CWE-119 - Memory corruption

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

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to non-paged pool overflow in driver module in Intel Smart Sound Technology. A local attacker can trigger memory corruption and execute arbitrary code with administrative privileges.
