Details

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: mediatek: Avoid btusbmtkclaimisointf() NULL deref In btusbmtksetup(), we set btmtk_data->isopkt_intf to: usbifnumtoif(data->udev, MTKISOIFNUM) That function can return NULL in some cases. Even when it returns NULL, though, we still go on to call btusbmtkclaimisointf(). As of commit e9087e828827 ("Bluetooth: btusb: mediatek: Add locks for usbdriverclaiminterface()"), calling btusbmtkclaimisointf() when btmtk_data->isopkt_intf is NULL will cause a crash because we'll end up passing a bad pointer to devicelock(). Prior to that commit we'd pass the NULL pointer directly to usbdriverclaiminterface() which would detect it and return an error, which was handled. Resolve the crash in btusbmtkclaimisointf() by adding a NULL check at the start of the function. This makes the code handle a NULL btmtk_data->isopkt_intf the same way it did before the problematic commit (just with a slight change to the error message printed).
