Doc Text:
A flaw was found in the Linux kernel's NFC (Near Field Communication) subsystem, specifically within the `nxp-nci` driver. This flaw prevented General Purpose Input/Output (GPIO) pins from entering a sleep state, leading to a kernel `WARN_ON` condition. This issue could potentially cause system instability or unexpected behavior, impacting the reliability of the system.

Description OSIDB Bzimport 2026-04-24 15:03:27 UTC
In the Linux kernel, the following vulnerability has been resolved:

NFC: nxp-nci: allow GPIOs to sleep

Allow the firmware and enable GPIOs to sleep.

This fixes a `WARN_ON' and allows the driver to operate GPIOs which are
connected to I2C GPIO expanders.
