This affects the function __mtk_ppe_check_skb of the file drivers/net/ethernet/mediatek/mtk_ppe.c of the component Ethernet Handler. Such manipulation leads to use after free. The name of the patch is 17a5f6a78dc7b8db385de346092d7d9f9dc24df6. It is best practice to apply a patch to resolve this issue. No released Linux Kernel version was ever affected by this CVE."

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.
