Description OSIDB Bzimport 2025-05-20 16:01:16 UTC 
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.
