Title
libceph: replace BUG_ON with bounds check for map->max_osd
Summary
In the Linux kernel, the following vulnerability has been resolved:
libceph: replace BUG_ON with bounds check for map->max_osd
OSD indexes come from untrusted network packets. Boundary checks are
added to validate these against map->max_osd.

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.

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.
