Описание
A vulnerability was found in the igc_probe() function in the Linux kernel's igc driver, where an uninitialized netdev is logged during the probe process. This occurs because the igc_ptp_init() function is called before the netdev() register is called, resulting in a misleading log entry.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
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
