Description
A flaw was found in the Linux kernel's Intel Bluetooth driver. When processing Device Descriptor Configuration (DDC) records, the driver fails to properly validate record lengths, allowing integer wrapping and reading past buffer boundaries. An attacker capable of supplying crafted firmware data could trigger an out-of-bounds read, leading to a Denial of Service (DoS) via a system crash.
