GSD-2023-52606
Vulnerability from gsd - Updated: 2024-03-03 06:01Details
In the Linux kernel, the following vulnerability has been resolved:
powerpc/lib: Validate size for vector operations
Some of the fp/vmx code in sstep.c assume a certain maximum size for the
instructions being emulated. The size of those operations however is
determined separately in analyse_instr().
Add a check to validate the assumption on the maximum size of the
operations, so as to prevent any unintended kernel stack corruption.

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.
