CVE-2026-64503 Details
Description
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.
A vulnerability in the Linux kernel's handling of runtime power management (PM) for the KXSD9 accelerometer has been identified. The issue arises in the 'kxsd9_write_raw()' function, which improperly manages PM references. When a scale with a non-zero integer part is requested, the function returns an error without releasing the PM reference, leading to a PM usage counter leak. This leak prevents the device from entering an autosuspend state, causing potential power management issues.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
