1) Security restrictions bypass

EUVDB-ID: #VU66549

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-26373

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to non-transparent sharing of return predictor targets between contexts in Intel CPU processors. A local user can bypass the expected architecture isolation between contexts and gain access to sensitive information on the system.

Mitigation

Install update from vendor's website.

2) NULL pointer dereference

EUVDB-ID: #VU67979

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-31681

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error. A local user with privileges within the VMX process only can perform a denial of service (DoS) attack against the host.

Mitigation

Install update from vendor's website.
