Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: btintel: Check dsbr size from EFI variable<br /> <br /> Since the size of struct btintel_dsbr is already known, we can just<br /> start there instead of querying the EFI variable size. If the final<br /> result doesn&amp;#39;t match what we expect also fail. This fixes a stack buffer<br /> overflow when the EFI variable is larger than struct btintel_dsbr.
