CVE-2026-90056

Estado: RecibidaSin puntuar—

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.
