# CVE-2026-64493

> 3.1 LOW

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

iio: pressure: mpl115: fix runtime PM leak on read error

mpl115_read_raw() takes a runtime PM reference with pm_runtime_get_sync()
before reading the processed pressure or raw temperature, but on the read
error path it returns without calling pm_runtime_put_autosuspend(). Each
failed read therefore leaks a runtime PM reference and prevents the device
from autosuspending.

Drop the reference before checking the return value so both the success
and error paths are balanced.

## Patch verfügbar (OSV)

- Kernel ≥ 6.6.145
- Kernel ≥ 6.12.97
- Kernel ≥ 6.18.39
- Kernel ≥ 7.1.4
