CVE-2025-38619

Kernel panic via repeated DMA buffer deletion

Published Aug 22, 2025 · Updated Aug 5, 2026

List corruption in the J721E CSI2RX driver in Linux beginning with 6.7 allows attackers to trigger a kernel panic during DMA failure. The ti_csi2rx_dma_callback function marks a failed buffer done without first removing it from the DMA queue, so the next iteration retries the same entry and deletes it twice. Reachability requires the TI J721E CSI2RX driver and a DMA-start failure; the demonstrated consequence is a kernel panic that interrupts the system until reboot.
