Overview
CVE-2025-54326 describes a denial-of-service vulnerability affecting the camera driver within Samsung Mobile Processor Exynos 1280 and 2200. This vulnerability arises from the unnecessary registration of a hardware IP address within the camera device driver, which can lead to a NULL pointer dereference. Exploitation of this flaw can result in a denial of service, potentially rendering the camera functionality unusable.
Technical Details
The root cause of CVE-2025-54326 lies in how the Camera device driver manages hardware IP address registration. Specifically, under certain conditions, the driver attempts to register an IP address that is not properly initialized. When the driver subsequently attempts to dereference this NULL pointer, the system crashes, leading to a denial of service condition. The specific conditions triggering this unnecessary registration warrant further investigation to understand the complete attack surface.
CVSS Analysis
Currently, the severity and CVSS score for CVE-2025-54326 are listed as N/A. This might indicate that the vulnerability is still under investigation or that the scoring is not yet finalized. A complete CVSS score would take into consideration the attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact. Until a CVSS score is provided, it is recommended to treat this vulnerability with caution and apply any available patches as soon as possible.
Possible Impact
The exploitation of CVE-2025-54326 can have the following impacts:
- Denial of Service: The primary impact is a denial-of-service condition, rendering the camera functionality unavailable.
- Application Crash: The camera application may crash repeatedly, hindering user experience.
- Potential System Instability: While the reported impact is denial-of-service of the camera, crashes like this can, in some scenarios, lead to wider system instability depending on the system architecture.
Mitigation or Patch Steps
The recommended course of action is to apply the security patch released by Samsung. Check the Samsung Security Update page for your specific device model to determine if a patch is available. Applying the latest software updates is crucial to mitigate this and other security vulnerabilities.
- Check for Updates: Navigate to your device’s settings and check for available software updates.
