  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: fec: only stop PTP if it was initialized\n\nfec_ptp_init() is only called when fep->bufdesc_ex is available.\nHowever, fec_probe() unconditionally calls fec_ptp_stop() on the\nfailed_init path, and fec_drv_remove() unconditionally calls\nfec_ptp_stop() during device removal.\n\nCheck fep->bufdesc_ex before calling fec_ptp_stop() in both paths\nto avoid stopping PTP when it was not initialized.",
