Public exploitNot knownno public code found

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

Bluetooth: btintel: validate DDC record lengths

Parse DDC record lengths in unsigned storage so 0xFF does not wrap. Reject records smaller than the mandatory three-byte header, records exceeding U8_MAX, and records exceeding remaining firmware bytes before issuing Intel_Write_DDC.

This issue was reported by Claude Mythos.
