In the Linux kernel, the following vulnerability has been resolved:
net: fec: only stop PTP if it was initialized
fec_ptp_init() is only called when fep->bufdesc_ex is available.
However, fec_probe() unconditionally calls fec_ptp_stop() on the
failed_init path, and fec_drv_remove() unconditionally calls
fec_ptp_stop() during device removal.
Check fep->bufdesc_ex before calling fec_ptp_stop() in both paths
to avoid stopping PTP when it was not initialized.
