Vulnerability from github – Published: 2026-08-15 06:32 – Updated: 2026-08-17 06:33

Details

In the Linux kernel, the following vulnerability has been resolved:

mac802154: remove interfaces with RCU list deletion

Queue wake, stop, and disable paths walk local->interfaces under RCU. The bulk hardware teardown path removes entries with list_del(), so an asynchronous transmit completion can follow a poisoned list node in ieee802154_wake_queue().

Use list_del_rcu() as in the single-interface removal path. The following unregister_netdevice() waits for in-flight RCU readers before freeing the netdevice, so no separate grace-period wait is needed.

Severity

7.8 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
