Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

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.

Vulnerable software versions

IBM Cloud Pak System: 2.3.0.1 - 2.3.3.5

http://www.ibm.com/support/pages/node/6856999


Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

How the attacker can exploit this vulnerability?

The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.

The attacker would have to login to the system and perform certain actions in order to exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

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.
