CVE-2024-23973 (GCVE-0-2024-23973)

Vulnerability from cvelistv5 – Published: 2025-01-30 23:28 – Updated: 2025-08-26 21:08

Title

Silicon Labs Gecko OS HTTP GET Request Handling Stack-based Buffer Overflow

Summary

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HTTP GET requests. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device.

Severity ?
