In the Linux kernel, the following vulnerability has been resolved:Bluetooth: btrtl: Prevent potential NULL dereferenceThe btrtl_initialize() function checks that rtl_load_file() eitherhad an error or it loaded a zero length file. However, if it loadeda zero length file then the error code is not set correctly. Itresults in an error pointer vs NULL bug, followed by a NULL pointerdereference. This was detected by Smatch:drivers/bluetooth/btrtl.c:592 btrtl_initialize() warn: passing zero to 'ERR_PTR'
