Details

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

netfilter: nf_queue: fix possible use-after-free

Eric Dumazet says: The sock_hold() side seems suspect, because there is no guarantee that sk_refcnt is not already 0.

On failure, we cannot queue the packet and need to indicate an error. The packet will be dropped by the caller.

v2: split skb prefetch hunk into separate change

Severity

5.5 (Medium)

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.
