CVE-2026-90249: iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 0fc740c25c9abb25113398ebb58e2f2ce57741a7, 470edb012b1d9a4fba1cd59e329e60f0798c791a, 56fe8e5f313a64e458bb6f8b982de925345e21a7.

Low priority for now. Upgrade to Linux Linux 0fc740c25c9abb25113398ebb58e2f2ce57741a7, 470edb012b1d9a4fba1cd59e329e60f0798c791a, 56fe8e5f313a64e458bb6f8b982de925345e21a7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
