Title
vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans
Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans
During loopback communication, a dangling pointer can be created in
vsk->trans, potentially leading to a Use-After-Free condition. This
issue is resolved by initializing vsk->trans to NULL.

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.
