Description OSIDB Bzimport 2026-07-25 10:07:47 UTC
In the Linux kernel, the following vulnerability has been resolved:

iio: accel: kxsd9: fix runtime PM imbalance on write_raw() error

kxsd9_write_raw() takes a runtime PM reference with pm_runtime_get_sync()
but returns -EINVAL directly when a scale with a non-zero integer part is
requested, skipping the matching pm_runtime_put_autosuspend(). This leaks
a runtime PM usage-counter reference on every such write, after which the
device can no longer autosuspend.

Set the error code and fall through to the existing put instead of
returning early.
