CVE-2022-50400 Vulnerability Summary

CVE-2022-50400: In the Linux kernel, the following vulnerability has been resolved: staging: greybus: audio_helper: remove unused and wrong debugfs usage In the greybus audio_helper code, the debugfs file for the dapm has the potential to be removed and memory will be leaked. There is also the very real potential for this code to remove ALL debugfs entries from the system, and it seems like this is what will really happen if this code ever runs. This all is very wrong as the greybus audio driver did not create this debugfs file, the sound core did and controls the lifespan of it. So remove all of the debugfs logic from the audio_helper code as there's no way it could be correct. If this really is needed, it can come back with a fixup for the incorrect usage of the debugfs_lookup() call which is what caused this to be noticed at all.

Assessing the Risk of CVE-2022-50400

Access Complexity Graph

The exploitability of CVE-2022-50400 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2022-50400

No exploitability data is available for CVE-2022-50400.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2022-50400, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
