Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于在Bluetooth模块的btusb驱动中，MediaTek的特殊USB中断接口在ISO数据传输时需要在卸载HCI设备前释放，若在USB断开时未正确释放该接口，可能导致在注销HCI设备时引发内核崩溃。
