CVE-2025-37935: net: ethernet: mtk_eth_soc: fix SER panic with 4GB+ RAM

Published May 20, 2025

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: mtkethsoc: fix SER panic with 4GB+ RAM

If the mtkpollrx() function detects the MTKRESETTING flag, it will jump to releasedesc and refill the high word of the SDP on the 4GB RFB. Subsequently, mtkrxclean will process an incorrect SDP, leading to a panic.

Add patch from MediaTek's SDK to resolve this.
