Details

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

netfilter: nft_set_pipapo: clamp maximum map bucket size to INT_MAX

Otherwise, it is possible to hit WARN_ON_ONCE in __kvmalloc_node_noprof() when resizing hashtable because __GFP_NOWARN is unset.

Similar to:

b541ba7d1f5a ("netfilter: conntrack: clamp maximum hashtable size to INT_MAX")

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.
