Description
A flaw was found in the Linux kernel's net: phy: micrel component. Specifically, within the lan8814_get_sig_rx() and lan8814_get_sig_tx() functions, a null pointer dereference can occur if ptp_parse_header() returns a NULL ptp_header due to an abnormal or corrupted packet. A remote attacker could exploit this by sending specially crafted network packets, leading to a system crash and a denial of service.
