CVE-2026-53215

A flaw was found in the Linux kernel's mvpp2 network driver. This vulnerability occurs due to incorrect handling of receive (RX) buffers, where a buffer is returned to the hardware Buffer Manager (BM) pool after it has been passed to the eXpress Data Path (XDP) or attached to a socket buffer (skb). This allows hardware Direct Memory Access (DMA) operations into memory that is no longer controlled by the RX ring, potentially leading to memory corruption.
