Remote code execution via RX buffer reuse
Published Jun 25, 2026 · Updated Jun 25, 2026
Memory corruption in the Linux Kernel mvpp2 driver allows remote attackers to execute code by sending packets under RX pressure. The mvpp2_rx error path returns a descriptor buffer to the hardware BM pool after XDP or skb handling has retired it, permitting DMA into reused kernel memory. Exploitation requires an mvpp2-based network interface and RX/refill pressure sufficient to make mvpp2_rx_refill fail; successful corruption permits disclosure, code execution, or a kernel panic.
