In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_event: validate LE Set CIG Parameters response

The Command Complete dispatch validates only the fixed part of the LE Set
CIG Parameters response. After that part is pulled from the skb,
hci_cc_le_set_cig_params() trusts num_handles and reads each entry in the
trailing handle array.

Matching num_handles against the command's num_cis does not guarantee
that the response contains the advertised handles. A truncated response
from a malfunctioning controller can therefore make the handler read
beyond the skb data.

Validate that the remaining skb data contains all advertised handles.
Include this in the existing response validation so malformed responses
also follow the established CIG failure handling.
