Overview
CVE-2025-58303 is a high-severity use-after-free (UAF) vulnerability identified in the screen recording framework module of a specific system. A successful exploit of this vulnerability can lead to unpredictable behavior and potentially impact system availability.
Technical Details
The vulnerability stems from improper memory management within the screen recording framework. Specifically, a memory location is freed while it is still being referenced. Subsequent access to this freed memory can result in arbitrary code execution or a denial-of-service condition. The exact trigger conditions require further investigation, but the vulnerability has been confirmed and assigned CVE-2025-58303.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) v3.0 score for CVE-2025-58303 is 8.4 (High).
- Attack Vector (AV): Network (N) – The vulnerability can be exploited remotely.
- Attack Complexity (AC): High (H) – Specialized access conditions or extenuating circumstances exist.
- Privileges Required (PR): None (N) – No privileges are required to perform an attack.
- User Interaction (UI): Required (R) – User interaction is required to trigger the vulnerability.
- Scope (S): Unchanged (U) – An exploited vulnerability can only affect resources managed by the same security authority.
- Confidentiality (C): None (N) – There is no loss of confidentiality.
- Integrity (I): None (N) – There is no loss of integrity.
- Availability (A): High (H) – There is a total loss of availability, or access to all resources is lost.
Possible Impact
Successful exploitation of CVE-2025-58303 can lead to:
- Denial of Service (DoS): The most likely outcome is a system crash, rendering the device or application unusable.
- Unpredictable Behavior: Due to memory corruption, the system might exhibit unexpected and unstable behavior.
- Potential for Code Execution: While not explicitly confirmed, UAF vulnerabilities can sometimes be leveraged for arbitrary code execution under specific circumstances, potentially leading to further compromise.
Mitigation and Patch Steps
The vendor, Huawei, has released a security bulletin addressing this vulnerability. Users are strongly advised to apply the recommended patch as soon as possible. Specific mitigation steps include:
- Apply the official patch: Refer to the Huawei security bulletin for instructions on obtaining and installing the patch.
- Disable the screen recording feature (if possible): As a temporary workaround, disabling the screen recording feature may reduce the attack surface until the patch can be applied. However, this may impact functionality.
