CVE-2026-98529: gpio: arizona: Fix runtime PM leak in arizona_gpio_direction_out()

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 39748357db26b20a02ea2a25ce48943e6c6d6286, 40c010c1866382cb63ba7497d6ec74fcc60ab9cf, 5c8e87f33b68557a725e72f34051299f55c6fa9e; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 39748357db26b20a02ea2a25ce48943e6c6d6286, 40c010c1866382cb63ba7497d6ec74fcc60ab9cf, 5c8e87f33b68557a725e72f34051299f55c6fa9e; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: gpio: arizona: Fix runtime PM leak in arizona_gpio_direction_out() Switching a persistent GPIO line from input to output acquires a runtime PM reference on the parent device, but if the subsequent regmap_update_bits() fails the reference is never dropped and no later direction_in() can balance it since the direction was never changed. Drop the reference on the update failure path.
