Vulnerability in Linux Kernel Affects spi: mpc52xx Controller

CVE-2026-46200

What is CVE-2026-46200?

A vulnerability has been identified in the Linux kernel related to the spi: mpc52xx controller. It stems from improper deregistration of the controller before the disabling and releasing of underlying resources such as interrupts and GPIOs during the driver unbinding process. This oversight could potentially lead to resource leaks or unexpected behavior in system operations, emphasizing the need for thorough checks and correct resource management in driver implementations. Updates addressing this issue ensure more robust handling of resource deallocation.
