Linux Distros Unpatched Vulnerability : CVE-2025-40282

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Bluetooth: 6lowpan: reset link-local header on ipv6 recv path Bluetooth 6lowpan.c netdev has headerops, so it must set link-local header for RX skb, otherwise...

CVE-2025-40282

In CVE-2025-40282, the Linux kernel Bluetooth 6lowpan implementation (net/bluetooth/6lowpan.c) is affected. The issue arises because netdev header_ops requires a link-local MAC header on RX skb, but the code resets this header only for the uncompressed IPv6 RX path; the compressed path already ha...
