In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_ll: Fix firmware leak on error path
Smatch reports:
drivers/bluetooth/hci_ll.c:587 download_firmware() warn:
'fw' from request_firmware() not released on lines: 544.
In download_firmware(), if request_firmware() succeeds but the returned
firmware content is invalid (no data or zero size), the function returns
without releasing the firmware, resulting in a resource leak.
Fix this by calling release_firmware() before returning when
request_firmware() succeeded but the firmware content is invalid.
