Published: August 15, 2018


Vulnerability identifier: #VU14411
CSH Severity: Low
CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]
CVE-ID: CVE-2018-3620
CWE-ID: CWE-200
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a local attacker to obtain potentially sensitive information.

The vulnerability exists due to an error in systems with microprocessors utilizing speculative execution and address translations . A local attacker can trigger terminal page fault, conduct side-channel attack and gain access to potentially sensitive information residing in the L1 data cache.
