Summary

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

iavf: Fix reset error handling

Do not call iavf_close in iavf_reset_task error handling. Doing so can lead to double call of napi_disable, which can lead to deadlock there. Removing VF would lead to iavf_remove task being stuck, because it requires crit_lock, which is held by iavf_close. Call iavf_disable_vf if reset fail, so that driver will clean up remaining invalid resources. During rapid VF resets, HW can fail to setup VF mailbox. Wrong error handling can lead to iavf_remove being stuck with: [ 5218.999087] iavf 0000:82:01.0: Failed to init adminq: -53 ...
