What it actually does
Race condition from use of RCU-unsafe __ipv6_get_lladdr after external locks removed in MLD code paths, causing invalid memory dereference and general protection fault during mld_ifc_work kernel processing.
Why it matters to the business
Kernel crashes and system stalls on affected Linux hosts disrupt network services and workloads; high availability impact with potential need for reboots, though no direct confidentiality or integrity loss.
How an attack unfolds
Attacker triggers IPv6 multicast group changes or MLD messages that schedule mld_ifc_work; the worker invokes add_grec which calls the unsafe address lookup without RCU protection, dereferencing freed or invalid memory and crashing the kernel.
How to fix it
Apply kernel patches restoring the RCU-safe ipv6_get_lladdr call. For chromium on Debian 12 update to version 126.0.6478.114-1~deb12u1 or later; monitor for backports in stable kernels and test in non-production first.
How to confirm the fix worked
Confirm kernel builds contain the RCU-safe ipv6_get_lladdr restoration; reproduce MLD interface change workloads and verify absence of GPF in dmesg; scan package versions against the fixed chromium 126.0.6478.114-1~deb12u1.
Typical attack path
- Send crafted IPv6 MLD packets or join/leave multicast groups
- Schedule mld_ifc_work kernel worker thread
- Execute add_grec and mld_newpack paths
- Call __ipv6_get_lladdr on potentially freed interface address structures
- Trigger general protection fault and kernel panic
How to detect it
Inspect kernel logs for general protection fault traces mentioning __ipv6_get_lladdr, mld_ifc_work, or add_grec; correlate with IPv6 multicast traffic spikes; check for kworker threads associated with MLD operations around crash timestamps.
- general protection fault.*__ipv6_get_lladdr
- mld_ifc_work
- RIP:.*__ipv6_get_lladdr
- Workqueue: mld mld_ifc_work
- dead0000000000
What your security team should do
- Prioritize kernel updates on all IPv6-enabled systems within 30 days given publication age
- Enable kernel panic logging and watchdog monitoring for early crash detection
- Restrict unnecessary IPv6 multicast exposure via firewall rules where feasible
- Review downstream package counts for broad ecosystem impact before rollout
The record
In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: use rcu-safe version of ipv6_get_lladdr() Some time ago 8965779d2c0e ("ipv6,mcast: always hold idev->lock before mca_lock") switched ipv6_get_lladdr() to __ipv6_get_lladdr(), which is rcu-unsafe version. That was OK, because idev->lock was held for these codepaths. In 88e2ca308094 ("mld: convert ifmcaddr6 to RCU") these external locks were removed, so we probably need to restore the original rcu-safe call. Otherwise, we occasionally get a machine crashed/stalled with the following in dmesg: [ 3405.966610][T230589] general protection fault, probably for non-canonical address 0xdead00000000008c: 0000 [#1] SMP NOPTI [ 3405.982083][T230589] CPU: 44 PID: 230589 Comm: kworker/44:3 Tainted: G O 5.15.19-cloudflare-2022.2.1 #1 [ 3405.998061][T230589] Hardware name: SUPA-COOL-SERV [ 3406.009552][T230589] Workqueue: mld mld_ifc_work [ 3406.017224][T230589] RIP: 0010:__ipv6_get_lladdr+0x34/0x60 [ 3406.025780][T230589] Code: 57 10 48 83 c7 08 48 89 e5 48 39 d7 74 3e 48 8d 82 38 ff ff ff eb 13 48 8b 90 d0 00 00 00 48 8d 82 38 ff ff ff 48 39 d7 74 22 <66> 83 78 32 20 77 1b 75 e4 89 ca 23 50 2c 75 dd 48 8b 50 08 48 8b [ 3406.055748][T230589] RSP: 0018:ffff94e4b3fc3d10 EFLAGS: 00010202 [ 3406.065617][T230589] RAX: dead00000000005a RBX: ffff94e4b3fc3d30 RCX: 0000000000000040 [ 3406.077477][T230589] RDX: dead000000000122 RSI: ffff94e4b3fc3d30 RDI: ffff8c3a31431008 [ 3406.089389][T230589] RBP: ffff94e4b3fc3d10 R08: 0000000000000000 R09: 0000000000000000 [ 3406.101445][T230589] R10: ffff8c3a31430000 R11: 000000000000000b R12: ffff8c2c37887100 [ 3406.113553][T230589] R13: ffff8c3a39537000 R14: 00000000000005dc R15: ffff8c3a31431000 [ 3406.125730][T230589] FS: 0000000000000000(0000) GS:ffff8c3b9fc80000(0000) knlGS:0000000000000000 [ 3406.138992][T230589] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 3406.149895][T230589] CR2: 00007f0dfea1db60 CR3: 000000387b5f2000 CR4: 0000000000350ee0 [ 3406.162421][T230589] Call Trace: [ 3406.170235][T230589] <TASK> [ 3406.177736][T230589] mld_newpack+0xfe/0x1a0 [ 3406.186686][T230589] add_grhead+0x87/0xa0 [ 3406.195498][T230589] add_grec+0x485/0x4e0 [ 3406.204310][T230589] ? newidle_balance+0x126/0x3f0 [ 3406.214024][T230589] mld_ifc_work+0x15d/0x450 [ 3406.223279][T230589] process_one_work+0x1e6/0x380 [ 3406.232982][T230589] worker_thread+0x50/0x3a0 [ 3406.242371][T230589] ? rescuer_thread+0x360/0x360 [ 3406.252175][T230589] kthread+0x127/0x150 [ 3406.261197][T230589] ? set_kthread_struct+0x40/0x40 [ 3406.271287][T230589] ret_from_fork+0x22/0x30 [ 3406.280812][T230589] </TASK> [ 3406.288937][T230589] Modules linked in: ...
