CVE-2024-38550

System crash via unchecked DRAM-info pointer

Published Jun 19, 2024 · Updated May 23, 2026

NULL pointer dereference in the Linux kernel's Kirkwood ASoC driver allows local users with high privileges to crash the system. kirkwood_dma_hw_params() dereferences the result of mv_mbus_dram_info() without checking for NULL when CONFIG_PLAT_ORION is not defined. Exploitation requires privileged local access to exercise audio hardware-parameter setup on a system using the Kirkwood driver, and the reported consequence is limited to availability.
