Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Out-of-bounds write

EUVDB-ID: #VU63166

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1158

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due the KVM implementation in Linux kernel does not properly perform guest page table updates in some situations. A remote user on the guest operating system can trigger memory corruption and perform a denial of service attack against the host OS.
