Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Linux kernel是美国等都是美国(Linux)基金会的产品。Linux kernel是开源操作系统Linux所使用的内核。SIG Bluetooth等都是蓝牙特别兴趣小组(SIG)标准组织的产品。Bluetooth是一种短距离无线技术标准，Symfony ux等都是(Symfony)开源的产品。ux是一个Symfony的JavaScript生态系统。 Linux kernel存在安全漏洞，该漏洞源于eir_get_service_data未处理NULL长度参数，可能导致空指针取消引用。
