Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Information disclosure

EUVDB-ID: #VU13850

Risk: Low

CVSSv4.0: 1.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-3693

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists in the design of most modern CPUs using speculative execution and branch prediction due to improper speculative execution of instructions. A local attacker can bypass bounds checks, trigger buffer overflow, perform arbitrary speculative execution and a side-channel attack to access sensitive memory information.

Vulnerable software versions

Intel CPU: All versions
