- Summary
- net: usb: lan78xx: Fix double free issue with interrupt buffer allocation
- 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
bufwas being freed twice: once implicitly throughusb_free_urb(dev->urb_intr)with theURB_FREE_BUFFERflag and again explicitly bykfree(buf). This caused a double free issue.To resolve this, reordered
kmalloc()andusb_alloc_urb()calls to simplify the initialization sequence and removed the redundantkfree(buf). Now,bufis allocated afterusb_alloc_urb(), ensuring it is correctly managed byusb_fill_int_urb()and freed byusb_free_urb()as intended. - Database specific
