driver core: platform: Don't read past the end of "driver_override" buffer
When printing the driver_override parameter when it is 4095 and 4094 bytes long, the printing code would access invalid memory because we need count+1 bytes for printing. Reject driver_override values of these lengths in driver_override_store(). This is in close analogy to commit 4efe874aace5 ("PCI: Don't read past the end of sysfs "driver_override" buffer") from Sasha Levin. Fixes: 3d713e0e382e ("driver core: platform: add device binding path 'driver_override'") Cc: stable@vger.kernel.org # v3.17+ Signed-off-by: Nicolai Stange <nstange@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
