Title

LineageOS 'msm_bus_dbg.c'空指针引用拒绝服务漏

Description

LineageOS是一个基于Android面向智能手机以及平板电脑的开源代码操作系统。android_kernel_huawei_msm8916是一个处理器。 LineageOS中的android_kernel_huawei_msm8916 2017-06-16及之前的版本的drivers/platform/msm/msm_bus/msm_bus_dbg.c文件的‘msm_bus_dbg_update_request_write’函数存在安全漏洞。攻击者可通过发送特制的/sys/kernel/debug/msm-bus-dbg/client-data/update-request写入请求利用该漏洞造成拒绝服务（空指针逆向引用和应用程序崩溃）。
