9.8

CVSS v3.1

Official Description

In cd_CodeMsg of cd_codec.c, there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-225178325References: N/A

Risk Analysis

A missing bounds check in the Android kernel's codec component leads to an out-of-bounds write, potentially enabling remote code execution. This critical 9.8-rated flaw does not require user interaction or elevated privileges to exploit.

No public exploit is known, and it is not in the CISA KEV. The vulnerability is remotely exploitable with low complexity.

Recommended Action

Apply the latest Android security patches provided by the device manufacturer. Ensure the system is updated to the most recent security patch level.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2022-20400 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
