In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btrtl: Don't leak return code when parsing firmware format v2
When key_id from chip is zero, rtlbt_parse_firmware_v2() intentionally
ignores all security headers. However, the implementation simply breaks
from a switch statement and leaks uninitialized return code `rc' (if the
first section is a security one) or the previous section's `rc'.
Fix it by really skipping a loop with `continue'. For consistency and
readability, also do the same for the default case.
