Vulnerability from fkie_nvd - Published: 2025-12-06 22:15 - Updated: 2026-10-15 19:10
Severity
8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: 6lowpan: reset link-local header on ipv6 recv path Bluetooth 6lowpan.c netdev has header_ops, so it must set link-local header for RX skb, otherwise things crash, eg. with AF_PACKET SOCK_RAW Add missing skb_reset_mac_header() for uncompressed ipv6 RX path. For the compressed one, it is done in lowpan_header_decompress(). Log: (BlueZ 6lowpan-tester Client Recv Raw - Success) ------ kernel BUG at net/core/skbuff.c:212! Call Trace: <IRQ> ... packet_rcv (net/packet/af_packet.c:2152) ... <TASK> __local_bh_enable_ip (kernel/softirq.c:407) netif_rx (net/core/dev.c:5648) chan_recv_cb (net/bluetooth/6lowpan.c:294 net/bluetooth/6lowpan.c:359) ------
