GHSA-G85Q-82H3-FMH4

Vulnerability from github – Published: 2026-10-06 09:31 – Updated: 2026-10-06 09:31

Details

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

wifi: virt_wifi: free skb when disconnected

When the simulated link is disconnected, virt_wifi_start_xmit() returns NET_XMIT_DROP without freeing the skb. dev_hard_start_xmit() treats this return value as consumed, so every packet sent while disconnected leaks its skb.

Free the skb before returning the drop status.

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.
