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...

CVE-2026-13351

Zephyr's IPv6 network stack can be prevented from receiving or processing future incoming packets by sending a small number of maliciously fragmented IPv6 packets. When such a packet is handled by the fragment-header processing path, the associated RX network packet buffer allocated from a memory...

CVE-2026-53215

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error path returns the current descriptor buffer to the hardware BM pool. That is only valid while the driver still owns the buffer. mvpp2rxrefill can fail after the...

CVE-2026-53215

CVE-2026-53215 affects the Linux kernel mvpp2 driver: the RX path could return a descriptor buffer to the hardware Buffer Manager after it had been handed to XDP or an skb, allowing DMA into memory no longer owned by the RX ring. Root cause is improper handling of RX buffers in mvpp2_rx_refill() ...
