- Summary
- net: wwan: mhi: fix memory leak in mhi_mbim_dellink
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: wwan: mhi: fix memory leak in mhimbimdellink
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 sets needsfreenetdev to true when registers network device, which makes netdev subsystem call freenetdev() automatically after unregisternetdevice().
