Details

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

net: usb: lan78xx: Fix double free issue with interrupt buffer allocation

In lan78xx_probe(), the buffer buf was being freed twice: once implicitly through usb_free_urb(dev->urb_intr) with the URB_FREE_BUFFER flag and again explicitly by kfree(buf). This caused a double free issue.

To resolve this, reordered kmalloc() and usb_alloc_urb() calls to simplify the initialization sequence and removed the redundant kfree(buf). Now, buf is allocated after usb_alloc_urb(), ensuring it is correctly managed by usb_fill_int_urb() and freed by usb_free_urb() as intended.

Severity

7.8 (High)

This caused\na double free issue.\n\nTo resolve this, reordered `kmalloc()` and `usb_alloc_urb()` calls to\nsimplify the initialization sequence and removed the redundant\n`kfree(buf)`.  Now, `buf` is allocated after `usb_alloc_urb()`, ensuring\nit is correctly managed by  `usb_fill_int_urb()` and freed by\n`usb_free_urb()` as intended."

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.
