What it is

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

ice: add missing ice_deinit_hw() in devlink reinit path

devlink-reload results in ice_init_hw failed error, and then removing

the ice driver causes a NULL pointer dereference.

[ +0.102213] ice 0000:ca:00.0: ice_init_hw failed: -16

...

[ +0.000001] Call Trace:

[ +0.000003] <TASK>

[ +0.000006] ice_unload+0x8f/0x100 [ice]

[ +0.000081] ice_remove+0xba/0x300 [ice]

Commit 1390b8b3d2be ("ice: remove duplicate call to ice_deinit_hw() on

error paths") removed ice_deinit_hw() from ice_deinit_dev(). As a result

ice_devlink_reinit_down() no longer calls ice_deinit_hw(), but

ice_devlink_reinit_up() still calls ice_init_hw(). Since the control

queues are not uninitialized, ice_init_hw() fails with -EBUSY.

Add ice_deinit_hw() to ice_devlink_reinit_down() to correspond with

ice_init_hw() in ice_devlink_reinit_up().
