CVE-2024-26790

SoC hang via unprefetched unaligned QDMA reads

Published Apr 4, 2024 · Updated May 11, 2026

Denial of service in the Linux fsl-qdma driver allows local users to hang an LS1028A SoC via 16-byte unaligned QDMA reads. The source descriptor omits its prefetchable bit, allowing an unaligned QDMA read to stall in the Network On-Chip and create a deadlock. Exploitation requires local low-privileged access, LS1028A hardware, and QDMA activity; the resulting deadlock interrupts system availability.
