CVE-2026-31687
Description
A flaw was found in the Linux kernel's OMAP General Purpose Input/Output (GPIO) driver. The omap_mpuio_driver is incorrectly registered from within the omap_gpio_probe() function while a device lock is already held. This can lead to a potential deadlock condition, which a local attacker could exploit to cause a system hang, resulting in a Denial of Service (DoS).
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Other); DoS: Crash, Exit, or Restart
Each thread of execution will "hang" and prevent tasks from completing. In some cases, CPU consumption may occur if a lock check occurs in a tight loop.
