Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the multi-thread race condition by identifying, reporting, and correcting the improper synchronization flaw in the card framework module via vendor patches.
Prevents unauthorized information transfer and corruption via shared system resources exploited by the concurrent execution race condition.
Protects system memory from unauthorized modification or access that could result from the race condition's integrity and availability impacts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Local race condition (CWE-362) with PR:N and high integrity/availability impact enables local privilege escalation via exploitation of the vulnerable card framework component.
NVD Description
Multi-thread race condition vulnerability in the card framework module. Impact: Successful exploitation of this vulnerability may affect availability.
Deeper analysisAI
CVE-2025-68956 is a multi-thread race condition vulnerability, classified under CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization), in the card framework module. Published on 2026-01-14, it carries a CVSS v3.1 base score of 8.0 (AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H) and primarily affects availability, though the vector indicates potential for low confidentiality impact alongside high integrity and availability impacts. The vulnerability impacts Huawei consumer products, as indicated by support bulletins for general consumer devices, laptops, and wearables.
A local attacker (AV:L) with no privileges required (PR:N) can exploit this vulnerability through low-complexity attacks (AC:L) that demand no user interaction (UI:N). Scope remains unchanged (S:U). Successful exploitation allows limited unauthorized disclosure of information (C:L), high disruption to data integrity (I:H), and high denial of service effects (A:H), potentially leading to system instability or corruption in affected Huawei devices.
Huawei has issued security bulletins for this CVE on consumer support pages dated January 2026, covering general consumer products (https://consumer.huawei.com/en/support/bulletin/2026/1/), laptops (https://consumer.huawei.com/en/support/bulletinlaptops/2026/1/), and wearables (https://consumer.huawei.com/en/support/bulletinwearables/2026/1/). These advisories provide details on mitigation for impacted devices.
