- Summary
- net: mhi: Fix memory leak in mhi_net_dellink()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: mhi: Fix memory leak in mhinetdellink()
MHI driver registers network device without setting the needsfreenetdev flag, and does NOT call free_netdev() when unregisters network device, which causes a memory leak.
This patch calls freenetdev() to fix it since netdevpriv is used after unregister.
