Vulnerability from github – Published: 2024-05-01 06:31 – Updated: 2024-07-03 18:37

Details

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

crypto: iaa - Fix nr_cpus < nr_iaa case

If nr_cpus < nr_iaa, the calculated cpus_per_iaa will be 0, which causes a divide-by-0 in rebalance_wq_table().

Make sure cpus_per_iaa is 1 in that case, and also in the nr_iaa == 0 case, even though cpus_per_iaa is never used if nr_iaa == 0, for paranoia.

Severity

8.4 (High)

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.
