Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Processor optimization removal or modification of security-critical code

EUVDB-ID: #VU65220

Risk: Low

CVSSv3.1: 4.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-29901

CWE-ID: CWE-1037 - Processor optimization removal or modification of security-critical code

Exploit availability: No

Description

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

The vulnerability exists due to the way non-transparent sharing of branch predictor targets between contexts. A local user can exploit the vulnerability to gain access to sensitive information.

Mitigation

Install update from vendor's website.

Vulnerable software versions

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.

Is there known malware, which exploits this vulnerability?

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

2) Processor optimization removal or modification of security-critical code

EUVDB-ID: #VU65221

Risk: Low

CVSSv3.1: 4.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-28693

CWE-ID: CWE-1037 - Processor optimization removal or modification of security-critical code

Exploit availability: No

Description

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

The vulnerability exists due to unprotected alternative channel of return branch target prediction. A local user can gain access to sensitive information.

Mitigation

Install update from vendor's website.

3) Type Confusion

EUVDB-ID: #VU65219

Risk: Low

CVSSv3.1: 2.2 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-23816

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

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

The vulnerability exists due to a branch type confusion. A local user can force the branch predictor to predict the wrong branch type and gain access to sensitive information.

Mitigation

Install update from vendor's website.
