Linux Kernel Vulnerability in Pressure Sensor Driver by Linux Foundation

CVE-2026-64493

What is CVE-2026-64493?

A vulnerability in the Linux kernel's mpl115 pressure sensor driver can lead to leaks in runtime power management references. The issue arises when the mpl115_read_raw() function acquires a runtime PM reference but does not release it in the event of a read error, preventing proper device autosuspension. This flaw can impact system performance by keeping the device unnecessarily active, highlighting the importance of correcting both success and error paths in driver implementations.
