Description
A flaw was found in the Linux kernel's MediaTek Bluetooth drivers. The drivers fail to properly validate the length of incoming Wireless Management Task (WMT) event packets before accessing their data fields. A malicious or compromised device could transmit a truncated or malformed event, causing an out-of-bounds memory read that can lead to a system crash, resulting in a Denial of Service (DoS), or potentially expose sensitive memory data.
