CVE-2023-53750

Out-of-bounds read via one-entry pad configuration

Published Dec 8, 2025 · Updated May 11, 2026

An out-of-bounds read in the Freescale pinctrl driver in Linux kernel 6.2 allows local users to trigger a memory-boundary violation. imx_pinconf_set_scu reads configs[1] into conf before checking num_configs, so a one-entry pad-wakeup configuration is read past its boundary. Reachability depends on a Freescale pinctrl-scu platform invoking pad wakeup with exactly one configuration entry; no more specific runtime consequence is published.
