Vulnerability from cvelistv5 – Published: 2025-09-15 14:02 – Updated: 2026-08-05 08:57

Title

igb: Do not free q_vector unless new one was allocated

Summary

In the Linux kernel, the following vulnerability has been resolved: igb: Do not free q_vector unless new one was allocated Avoid potential use-after-free condition under memory pressure. If the kzalloc() fails, q_vector will be freed but left in the original adapter->q_vector[v_idx] array position.

Severity

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.
