Currently, the vulnerability status is undergoing analysis, and there is no confirmed public exploit. However, due to the critical nature of this vulnerability, organizations should prioritize patching immediately.
Organizations using ELECOM wireless LAN access point devices should take immediate action to assess their exposure and apply any available patches or updates as soon as they are provided by the vendor.
Vulnerability Details
The vulnerability identified as CVE-2026-24465 is characterized as a stack-based buffer overflow in ELECOM wireless LAN access point devices. This flaw allows crafted packets to execute arbitrary code. It has a CVSS version 4.0 score of 9.3, classifying it as critical, with high impacts on confidentiality, integrity, and availability.
The vulnerability was published on February 3, 2026, and is linked to CWE-121, indicating improper restriction of operations within the bounds of a memory buffer. As this vulnerability is still undergoing analysis, detailed vendor-specific mitigations are yet to be released.
Technical Analysis
The root cause of this vulnerability is a stack-based buffer overflow, which occurs when the program writes more data to a buffer located on the stack than it can hold. Attackers may leverage this flaw by sending specially crafted packets to the affected device.
The attack vector is classified as network-based, which means that the attacker does not require physical access to the device to initiate the attack. The attack complexity is rated low, indicating that the exploit can be executed with minimal effort.
No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impact on confidentiality, integrity, and availability is high, making this vulnerability particularly dangerous.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability is significant. Organizations utilizing ELECOM wireless LAN access point devices face potential unauthorized access and control of their networks, which could lead to data breaches and loss of sensitive information.
The blast radius for this vulnerability is extensive due to the widespread use of wireless LAN access points in organizational networks. Organizations should assess the urgency based on the CVSS score of 9.3, indicating that immediate action is necessary.
Given that this vulnerability is not currently listed in the Known Exploited Vulnerabilities (KEV) catalog, organizations should remain vigilant and monitor for updates from the vendor regarding patches and remediation strategies.
