zephyrproject-rtos Zephyr up to 4.1.0 BLE Connection Response security check

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability has been found in zephyrproject-rtos Zephyr up to 4.1.0 and classified as problematic. Affected by this vulnerability is an unknown part of the component BLE Connection Response Handler. The manipulation with an unknown input leads to a security check vulnerability. The CWE definition for the vulnerability is CWE-358. The product does not implement or incorrectly implements one or more security-relevant checks as specified by the design of a standardized algorithm, protocol, or technique. As an impact it is known to affect availability. The summary by CVE is:

The function responsible for handling BLE connection responses does not verify whether a response is expected—that is, whether the device has initiated a connection request. Instead, it relies solely on identifier matching.

The advisory is shared at github.com. This vulnerability is known as CVE-2025-10457 since 09/15/2025. The exploitation appears to be easy. The attack needs to be done within the local network. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.
