  3. CVE-2024-50097
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: fec: no guardar el estado de PTP si PTP no es compatible. Algunas plataformas (como i.MX25 e i.MX27) no son compatibles con PTP, por lo que en estas plataformas no se llama a fec_ptp_init() y los miembros relacionados en fep no se inicializan. Sin embargo, se llama a fec_ptp_save_state() de forma incondicional, lo que hace que el kernel entre en pánico. Por lo tanto, agregue una condición para que no se llame a fec_ptp_save_state() si PTP no es compatible.
