CVE-2025-37935

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

State: Published
Severity: 9.8 Critical
Published: May 20, 2025
Updated: Aug 5, 2026
Reserved: Apr 16, 2025

Description

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.
