GHSA-CC2M-7VJR-3594

Vulnerability from github – Published: 2026-09-16 12:30 – Updated: 2026-09-16 12:30

Details

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

usb: image: mdc800: change kmalloc() to kzalloc()

Change the kmalloc() calls in usb_mdc800_init() for irq_urb_buffer and download_urb_buffer to kzalloc(), avoiding potential stack leaks if a shorter message is received in mdc800_usb_irq() and mdc800_usb_download_notify()

Detection rules are retrieved from Rulezet.

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.
