CVE-2025-40113

System crash via incomplete ADSP DTB shutdown

Published Nov 12, 2025 · Updated Nov 12, 2025

Improper firmware shutdown in Linux 6.9 through 6.17.2 allows attackers to crash X1E systems via unspecified vectors. The qcom_q6v5_pas driver shuts down the main lite PAS ID before loading new ADSP firmware but leaves the matching DTB lite PAS ID running. Accessing or reusing adsp_boot_dtb_mem then crashes the system; the path is specific to X1E hardware, and the running lite firmware state is not detectable.
