CVE-2025-37935

Medium

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtk_eth_soc: fix SER panic with 4GB+ RAM If the mtk_poll_rx() function detects the MTK_RESETTING flag, it will jump to release_desc and refill the high word of the SDP on the 4GB RFB. Subsequently, mtk_rx_clean will process an incorrect SDP, leading to a panic. Add patch from MediaTek's SDK to resolve this.
