Vulnerability from github – Published: 2025-03-18 21:31 – Updated: 2025-09-29 12:30

Details

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

media: staging: media: zoran: calculate the right buffer number for zoran_reap_stat_com

On the case tmp_dcim=1, the index of buffer is miscalculated. This generate a NULL pointer dereference later.

So let's fix the calcul and add a check to prevent this to reappear.

Severity

5.5 (Medium)

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.
