Overview
CVE-2025-58307 is a medium severity Use-After-Free (UAF) vulnerability discovered in a widely used screen recording framework module. This vulnerability, published on 2025-11-28, could allow an attacker to compromise system availability. A successful exploit could lead to application crashes or potentially more severe consequences depending on the specific implementation and permissions of the affected application.
Technical Details
The Use-After-Free vulnerability (CVE-2025-58307) occurs when the screen recording framework module attempts to access memory that has already been freed. This can happen due to various programming errors, such as:
- Incorrect object lifecycle management
- Race conditions in multi-threaded environments
- Improper handling of asynchronous events
When the framework tries to access this freed memory, it can lead to unpredictable behavior, including crashes or, in some cases, the ability to execute arbitrary code. The exact mechanism by which the vulnerability can be exploited depends on the specific details of the code, which are often kept private to avoid widespread exploitation before patches are available.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-58307 a score of 6.4, indicating a MEDIUM severity. This score reflects the potential impact on system availability. The CVSS vector typically includes components that factor in exploitability and impact metrics. The specific vector string is not available in the initial report, but would further clarify the breakdown of the score (e.g., Attack Vector, Attack Complexity, Privileges Required, User Interaction, Scope, Confidentiality Impact, Integrity Impact, Availability Impact).
Possible Impact
Successful exploitation of CVE-2025-58307 can lead to the following:
- Application Crashes: The most common outcome is an application crash due to the invalid memory access.
- Denial of Service (DoS): Repeated crashes can lead to a denial of service, preventing users from utilizing the screen recording functionality.
- Potential Code Execution (Limited): While not the primary impact, under certain circumstances, attackers could potentially leverage the UAF to execute arbitrary code. However, this is less likely and depends on the specific memory layout and exploitation techniques.
Mitigation and Patch Steps
The recommended mitigation strategy is to apply the patch provided by the vendor. Huawei has released a security bulletin addressing this vulnerability:
- Apply the Patch: Immediately install the security patch referenced in the Huawei security bulletin to address the vulnerability.
- Monitor for Updates: Regularly monitor for new security updates from the vendor.
- Disable Screen Recording (Temporary): As a temporary measure, consider disabling screen recording functionality if possible, until the patch can be applied.
