CVE-2025-40282 is a Linux kernel vulnerability affecting Bluetooth 6LoWPAN support. The bug occurs when the kernel fails to reset the link-local (MAC) header on received IPv6 packets in the uncompressed receive path. A crafted packet can trigger a kernel BUG and crash the host if the 6LoWPAN Bluetooth stack and packet sockets are present. A patch has been issued to fix the issue by ensuring skb_reset_mac_header is called properly. This tag covers discussions about the vulnerability, its impact on Linux systems, and the patch that prevents crashes.
