CVE-2024-50097 Information

Description

In the Linux kernel the following vulnerability has been resolved:

net: fec: don’t save PTP state if PTP is unsupported

Some platforms (such as i.MX25 and i.MX27) do not support PTP so on these platforms fec_ptp_init() is not called and the related members in fep are not initialized. However fec_ptp_save_state() is called unconditionally which causes the kernel to panic. Therefore add a condition so that fec_ptp_save_state() is not called if PTP is not supported.
