A flaw was found in the Linux kernel's Intel Bluetooth PCIe driver. An integer overflow vulnerability exists in the packet reception function when calculating the total length of incoming Bluetooth frames. An adjacent attacker within Bluetooth range could exploit this flaw by transmitting specially crafted frames with large data length values, bypassing buffer validation checks. This vulnerability can lead to improper packet truncation and cause a Denial of Service (DoS).
