Vulnerability from fkie_nvd - Published: 2026-09-17 17:16 - Updated: 2026-09-17 17:16
Severity
Summary
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.
