About this tag
The bluetooth 6lowpan tag on WindowsForum.com covers Linux kernel vulnerabilities and patches related to the Bluetooth 6LoWPAN subsystem, which enables IPv6 communication over Bluetooth Low Energy. Recent discussions focus on two CVEs: CVE-2025-22007, a denial-of-service bug in chan_alloc_skb_cb() that can cause kernel NULL-pointer faults, and CVE-2025-40282, a crash triggered by missing MAC header reset in the uncompressed receive path. Both issues have been patched in the Linux kernel. Content includes technical analysis of error handling, packet processing, and the impact on systems using Bluetooth 6LoWPAN.

    CVE-2025-22007: Linux Bluetooth 6LoWPAN DoS Fix in chan_alloc_skb_cb

    A recently assigned Linux-kernel vulnerability, CVE-2025-22007, fixes a subtle but consequential Bluetooth error-handling bug in net/bluetooth/6lowpan.c where the function chan_alloc_skb_cb() could return NULL instead of the kernel’s standard error-pointer value; that incorrect return allows a...

    Linux Kernel 6LoWPAN Bug CVE-2025-40282 Patch Prevents Crashes

    A subtle but real kernel bug affecting Bluetooth 6LoWPAN support in Linux — tracked as CVE-2025-40282 — has been identified and patched: the kernel failed to reset the link-local (MAC) header on received IPv6 packets in the uncompressed receive path, allowing a crafted packet to trigger a kernel...
