AI-suggested
A fix is available that replaces pm_runtime_get_sync() with pm_runtime_resume_and_get() and returns early on failure to prevent unpowered register accesses. Users should apply the official kernel updates that include this patch to remediate the vulnerability.
Description
A vulnerability in the Linux kernel's ASoC rockchip_pdm driver was resolved. The issue involved improper handling of runtime power management resume failures in the rockchip_pdm_set_fmt() function, which ignored the failure return value and proceeded to access hardware registers in an undefined device state. This could lead to unpowered register accesses. The fix replaced pm_runtime_get_sync() with pm_runtime_resume_and_get() and added early return on failure to prevent such accesses.
