Overview

What is CVE-2026-90249?

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

iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes

The IIO core does not filter duplicate writes to the event enable attribute, so writing the same value twice invokes write_event_config() twice. Enabling twice leaks a runtime PM reference, preventing the device from ever suspending again; disabling twice underflows the usage count and triggers a "Runtime PM usage count underflow" warning.

Bail out early when the requested state matches the current state. While at it, switch to pm_runtime_resume_and_get() so a failed resume is propagated to userspace instead of silently marking the event enabled.
