Details

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

wifi: wilc1000: add missing unregister_netdev() in wilc_netdev_ifc_init()

Fault injection test reports this issue:

kernel BUG at net/core/dev.c:10731! invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI Call Trace: wilc_netdev_ifc_init+0x19f/0x220 [wilc1000 884bf126e9e98af6a708f266a8dffd53f99e4bf5] wilc_cfg80211_init+0x30c/0x380 [wilc1000 884bf126e9e98af6a708f266a8dffd53f99e4bf5] wilc_bus_probe+0xad/0x2b0 [wilc1000_spi 1520a7539b6589cc6cde2ae826a523a33f8bacff] spi_probe+0xe4/0x140 really_probe+0x17e/0x3f0 __driver_probe_device+0xe3/0x170 driver_probe_device+0x49/0x120

The root case here is alloc_ordered_workqueue() fails, but cfg80211_unregister_netdevice() or unregister_netdev() not be called in error handling path. To fix add unregister_netdev goto lable to add the unregister operation in error handling path.
