CyberRota Analysis
AI-GeneratedThe vulnerability affects the Bluetooth subsystem in the Linux kernel, specifically in the hci_aml driver, where improper validation of firmware segment lengths can lead to buffer overflows. This flaw may allow attackers to exploit truncated or inconsistent firmware images, potentially leading to arbitrary code execution or system crashes. Organizations using Linux systems with Bluetooth capabilities should prioritize addressing this issue to mitigate risks associated with firmware handling.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_aml: validate firmware segment lengths aml_download_firmware() reads two lengths from the firmware header and uses them to build pointers before checking that the header and segment data are present. A truncated or inconsistent firmware image can make the driver read past firmware->data while constructing TCI commands. Reject images shorter than the header and ensure that the ICCM and DCCM ranges fit within the loaded firmware before downloading either segment.
