CVE-2025-44526: n/a
Realtek RTL8762EKF-EVB RTL8762E SDK V1.4.0 was discovered to utilize insufficient permission checks on critical fields within Bluetooth Low Energy (BLE) data packets. This issue allows attackers to cause a Denial of Service (DoS) via a crafted LL_Length_Req packet.
AI Analysis
Technical Summary
CVE-2025-44526 affects Realtek RTL8762EKF-EVB RTL8762E SDK version 1.4.0. The vulnerability arises from insufficient permission checks on critical fields in BLE data packets, specifically allowing an attacker to trigger a Denial of Service condition by crafting and sending a malicious LL_Length_Req packet. This issue is categorized under CWE-284 (Improper Access Control) and CWE-20 (Improper Input Validation). There is no evidence of known exploits in the wild, and no vendor patch or remediation information is provided.
Potential Impact
An attacker with access to the Bluetooth Low Energy interface can cause a Denial of Service, disrupting normal operation of the affected device or system. The vulnerability does not impact confidentiality or integrity but results in availability loss. The CVSS vector indicates the attack requires adjacent network access with low complexity and no privileges or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit exposure by controlling access to BLE interfaces and monitoring for anomalous LL_Length_Req packets if possible.
