CVE-2026-53217

A flaw was found in the Linux kernel's mvpp2 network driver. This issue occurs because the driver incorrectly synchronizes received RX data at the hardware packet offset. On systems with non-coherent Direct Memory Access DMA, this can lead to the Central Processing Unit CPU reading stale cache...
