CVE-2022-48705

Medium

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921e: fix crash in chip reset fail In case of drv own fail in reset, we may need to run mac_reset several times. The sequence would trigger system crash as the log below. Because we do not re-enable/schedule "tx_napi" before disable it again, the process would keep waiting for state change in napi_diable(). To avoid the problem and keep status synchronize for each run, goto final resource handling if drv own failed.
