Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Use After Free (CVE-ID: CVE-2023-49672)

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

The vulnerability exists due to a possible use after free due to a logic error within the ion driver in Kernel. A local application can perform a denial of service (DoS) attack.


2) Improper input validation (CVE-ID: CVE-2023-49671)

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

The vulnerability exists due to a possible improper input validation within the ion driver in Kernel. A local application can perform a denial of service (DoS) attack.


3) Out-of-bounds write (CVE-ID: CVE-2023-49670)

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

The vulnerability exists due to a possible out of bounds write due to a missing bounds check within the cp_dump driver in Kernel. A local application can perform a denial of service (DoS) attack.


4) Out-of-bounds write (CVE-ID: CVE-2023-49669)

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

The vulnerability exists due to a possible out of bounds write due to a missing bounds check within the cp_dump driver in Kernel. A local application can perform a denial of service (DoS) attack.


5) Out-of-bounds read (CVE-ID: CVE-2023-49668)

The vulnerability allows a local application to execute arbitrary code.

The vulnerability exists due to a possible out of bounds read due to a missing bounds check within the cp_dump driver in Kernel. A local application can execute arbitrary code.


6) Buffer over-read (CVE-ID: CVE-2023-49667)

The vulnerability allows a local application to execute arbitrary code.

The vulnerability exists due to a possible out of bounds read due to a missing bounds check within the cp dump driver in Kernel. A local application can execute arbitrary code.
