Details

In the Linux kernel, the following vulnerability has been resolved: media: mxl111sf: change mutexinit() location Syzbot reported, that mxl111sfctrlmsg() uses uninitialized mutex. The problem was in wrong mutexinit() location. Previous mutexinit(&state->msglock) call was in ->init() function, but dvbusbv2init() has this order of calls: dvbusbv2init() dvbusbv2adapterinit() dvbusbv2adapterfrontendinit() props->frontendattach() props->init() Since mxl111sf* devices call mxl111sfctrlmsg() in ->frontendattach() internally we need to initialize state->msglock before frontendattach(). To achieve it, ->probe() call added to all mxl111sf_* devices, which will simply initiaize mutex.
