The CVE-2025-54613 vulnerability stems from a flaw in the DetailDescriptionIterator within Huawei’s card management module. This iterator processes data structures detailing card components but lacks proper boundary checks and exception handling. When handling concurrent modifications or malformed input, the iterator may dereference null pointers or enter invalid states, leading to race conditions. Local attackers can exploit this by sending crafted requests to the card management interface, triggering failures without authentication. The iterator’s failure can cause memory corruption, use-after-free scenarios, or resource leaks, disrupting system stability. This affects confidentiality, integrity, and availability locally, as per the CVSS vector. The vulnerability is inherent in code paths where iteration occurs over dynamic lists without synchronization, allowing predictable crashes or data exposure. It primarily impacts systems relying on card management for hardware or software operations, with medium severity due to local access requirements.
Platform: Huawei
Version: Not specified
Vulnerability: Iterator failure
Severity: Medium
Date: 08/05/2025
Prediction: Patched Dec 2025
What Undercode Say:
Analytics
– `dmesg | grep card_management`
– `systemctl status huawei-card-service`
– `cat /proc/modules | grep card`
– Code snippet:
for (detail in details) {
if (detail == NULL) break;
}
How Exploit:
Send malformed requests locally to trigger iterator failure, causing crashes or memory corruption for denial of service.
Protection from this CVE
Apply Huawei patches, disable unused card services, implement input validation and synchronization locks in code.
Impact:
System instability, denial of service, potential information disclosure or privilege escalation locally.
