CVE-2023-20925 : What You Need to Know

This article provides detailed information about CVE-2023-20925, its impact, technical details, and mitigation strategies.

Understanding CVE-2023-20925

CVE-2023-20925 is a published CVE record related to a vulnerability identified in the Android operating system. The vulnerability specifically affects the Android kernel and has the potential for local privilege escalation without requiring any additional execution privileges or user interaction during exploitation.

What is CVE-2023-20925?

The vulnerability, documented in the setUclampMinLocked function within PowerSessionManager.cpp, poses a risk of memory corruption due to a use-after-free scenario. This memory corruption issue could be exploited to achieve local escalation of privilege on affected systems.

The Impact of CVE-2023-20925

If successfully exploited, CVE-2023-20925 could allow an attacker to elevate their privileges locally on an affected device running the vulnerable Android kernel. This elevation of privilege could enable the attacker to carry out unauthorized actions or access sensitive information on the compromised system.

Technical Details of CVE-2023-20925

The technical aspects of CVE-2023-20925 include the vulnerability description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description

The vulnerability in the setUclampMinLocked function within PowerSessionManager.cpp may result in memory corruption, leading to a use-after-free condition. This allows threat actors to potentially execute malicious code and escalate their privileges on the target system.

Affected Systems and Versions

The vulnerability impacts the Android operating system, specifically the Android kernel. Systems running the affected versions of the Android kernel are susceptible to exploitation if the necessary conditions are met.

Exploitation Mechanism

To exploit CVE-2023-20925, an attacker would need to craft a specific payload to trigger the use-after-free scenario within the setUclampMinLocked function. By successfully manipulating memory in this way, the attacker could achieve local privilege escalation on the targeted Android device.

Mitigation and Prevention

In response to CVE-2023-20925, it is crucial for users and organizations to take immediate steps to secure their systems and implement long-term security practices to safeguard against similar vulnerabilities in the future.

Immediate Steps to Take
