Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Type Confusion (CVE-ID: CVE-2022-23816)
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.
2) Type Confusion (CVE-ID: CVE-2022-23825)
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.
3) Security restrictions bypass (CVE-ID: CVE-2022-26373)
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.
4) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2022-28693)
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.
5) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2022-29901)
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.
