net: libwx: properly reset Rx ring descriptor

Summary

In the Linux kernel, the following vulnerability has been resolved: net: libwx: properly reset Rx ring descriptor When device reset is triggered by feature changes such as toggling Rx VLAN offload, wx->do_reset() is called to reinitialize Rx rings. The hardware descriptor ring may retain stale values from previous sessions. And only set the length to 0 in rx_desc[0] would result in building malformed SKBs. Fix it to ensure a clean slate after device reset. [ 549.186435] [ C16] ------------[ cut here ]------------ [ 549.186457] [ C16] kernel BUG at net/core/skbuff.c:2814!

Detection rules are retrieved from Rulezet.

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.
