What it actually does
The vulnerability causes excessive CPU time in batadv_purge_orig_ref() due to iteration over empty hash buckets without early exit, resulting in soft lockups and kernel workqueue stalls in the batman-adv module.
Why it matters to the business
Systems running affected Linux kernels with batman-adv enabled may experience sudden unresponsiveness or hangs during routine originator cleanup, disrupting network operations and requiring reboots in production environments.
How an attack unfolds
An attacker triggers repeated conditions that populate and then require purging of batman-adv originator tables (such as through crafted mesh packets or topology changes), forcing the purge function into prolonged execution without rescheduling, leading to watchdog-detected soft lockups.
How to fix it
Upgrade the Linux kernel to a version containing commit 79636f636126775436a11ee9cf00a9253a33ac11 in the stable tree; rebuild and deploy the updated kernel image across all affected systems.
How to confirm the fix worked
Confirm the running kernel includes commit 79636f636126775436a11ee9cf00a9253a33ac11 via git log or kernel version string; test batadv_purge_orig_ref() under load to verify absence of extended spinlock holds.
Typical attack path
- Enable or interact with batman-adv mesh networking on target
- Send crafted or high-volume batman-adv protocol packets to populate originator references
- Trigger periodic purge via workqueue to enter batadv_purge_orig_ref()
- Exploit empty bucket iteration to extend spinlock-held section beyond scheduling threshold
- Cause soft lockup and system degradation or crash
How to detect it
Review kernel logs for soft lockup messages mentioning batadv_purge_orig_ref or kworker threads in bat_events; inspect for repeated calls to spin_lock_bh in originator.c around line 1271.
What your security team should do
- Prioritize kernel upgrade to the fixed commit on all systems using batman-adv
- Monitor for soft lockup reports in dmesg related to batadv_purge_orig
- Temporarily disable batman-adv interfaces if immediate patching is not feasible
The record
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bypass empty buckets in batadv_purge_orig_ref() Many syzbot reports are pointing to soft lockups in batadv_purge_orig_ref() [1] Root cause is unknown, but we can avoid spending too much time there and perhaps get more interesting reports.
