Title
Bluetooth: btintel: validate DDC record lengths
Summary
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.
Severity
No CVSS data available.
