CVE-2026-64493
Description
A flaw was found in the Linux kernel's mpl115 pressure sensor driver. When a read error occurs in the mpl115_read_raw() function, the driver fails to properly release a Power Management (PM) reference. This oversight leads to a continuous leak of PM references with each failed read. The accumulation of these unreleased references can prevent the affected device from entering an autosuspend state, potentially leading to increased power consumption or other resource management issues.
