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.
