Vulnerability from github – Published: 2026-08-15 06:32 – Updated: 2026-08-23 15:32

Details

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

tracing/osnoise: Call synchronize_rcu() when unregistering

This ensures that any RCU readers traversing the instance list have finished, before releasing the reference on the tracer that the instance points to.

Severity

7.8 (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.

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.
