No CVSS vector from any source. Fix status from CNA and Red Hat.

Summary

Linux kernel versions from 4.3 are affected. The btintel Bluetooth driver's hardware error handler prints exception data from a 12-byte payload that is not guaranteed to be NUL-terminated, so the print can read past the end of the buffer. The fix bounds the print by the length of the received packet.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: fix buffer over-read in btintel_hw_error() The "Exception info %s" print uses skb->data + 1, but the 12-byte payload is not guaranteed to be NUL-terminated and can be read past its end. Bound the print with "%.*s" and skb->len - 1.
