CVE-2022-48778

Runtime power-management leak via skipped reference release

Published Jul 16, 2024 · Updated May 11, 2026

Reference-count leak in the Linux kernel GPMI NAND driver allows local users to prevent the controller from runtime-suspending. The gpmi_nfc_exec_op() error path returned when gpmi_nfc_apply_timings() failed without reaching pm_runtime_put_autosuspend(). Reachability requires a GPMI NAND controller and a timing-application failure; each failed operation leaves its runtime-PM usage reference elevated.
