Improper Resource Management in Linux Kernel Affects SPI Controller

CVE-2026-46226

What is CVE-2026-46226?

A vulnerability in the Linux kernel's SPI controller has been identified, where the controller's deregistration process was not properly managed before the release of underlying resources such as DMA. This oversight may lead to resource leaks and instability in the system. Properly addressing this issue involves ensuring that the deregistration of the controller occurs before any related resources are freed, thereby preventing potential complications in system performance.
