Vulnerability from cvelistv5 – Published: 2026-01-05 09:44 – Updated: 2026-05-11 21:52

Title

mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add()

Summary

In the Linux kernel, the following vulnerability has been resolved: mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add() In mt7615_mcu_wtbl_sta_add(), an skb sskb is allocated. If the subsequent call to mt76_connac_mcu_alloc_wtbl_req() fails, the function returns an error without freeing sskb, leading to a memory leak. Fix this by calling dev_kfree_skb() on sskb in the error handling path to ensure it is properly released.

GHSA-RRCC-67M8-5VG7

Vulnerability from github – Published: 2026-01-05 12:30 – Updated: 2026-01-19 15:30

Details

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

mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add()

In mt7615_mcu_wtbl_sta_add(), an skb sskb is allocated. If the subsequent call to mt76_connac_mcu_alloc_wtbl_req() fails, the function returns an error without freeing sskb, leading to a memory leak.

Fix this by calling dev_kfree_skb() on sskb in the error handling path to ensure it is properly released.

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.
