Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) 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.


2) NULL pointer dereference (CVE-ID: CVE-2022-31681)

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.


3) Buffer overflow (CVE-ID: CVE-2022-31696)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in the way network socket are handled. A local privileged user can trigger memory corruption and execute arbitrary code with elevated privileges.


4) Heap-based buffer overflow (CVE-ID: CVE-2022-31699)

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

The vulnerability exists due to a boundary error in OpenSLP. A local user with restricted privileges within a sandbox process can trigger a heap overflow and gain access to sensitive information.



5) Deserialization of Untrusted Data (CVE-ID: CVE-2022-31680)

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data within the Platform services controller (PSC). A remote user with administrative privileges can pass specially crafted data to the controller and execute arbitrary code on the target system.
