Driver Registration Flaw in Linux Kernel Affecting OMAP Products

CVE-2026-31687

What is CVE-2026-31687?

A vulnerability exists in the Linux kernel relating to the registration of the omap_mpuio_driver during the probe callback of another driver. This practice not only contradicts established driver core conventions but also risks a deadlock condition when device locks are held. Furthermore, the omap_mpuio_driver lacks proper unregistration from the driver core, which could lead to resource leaks and instability when the module is unloaded. The vulnerability emphasizes the importance of adhering to correct driver lifecycle management and highlights potential risks in the implementation of device drivers within the Linux kernel.
