Description In the Linux kernel, the following vulnerability has been resolved: igc: fix a log entry using uninitialized netdev During successful probe, igc logs this: [ 5.133667] igc 0000:01:00.0 (unnamed net_device) (uninitialized): PHC added ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The reason is that igc_ptp_init() is called very early, even before register_netdev() has been called. So the netdev_info() call works on a partially uninitialized netdev. Fix this by calling igc_ptp_init() after register_netdev(), right after the media autosense check, just as in igb. Add a comment, just as in igb. Now the log message is fine: [ 5.200987] igc 0000:01:00.0 eth0: PHC added This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
