Details

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

netfs: Call invalidate_cache only if implemented

Many filesystems such as NFS and Ceph do not implement the invalidate_cache method. On those filesystems, if writing to the cache (NETFS_WRITE_TO_CACHE) fails for some reason, the kernel crashes like this:

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.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
