CVE-2026-46200
Description
A flaw was found in the Linux kernel's spi: mpc52xx driver. This vulnerability occurs because the controller is not properly deregistered before its underlying resources, such as interrupts and General Purpose Input/Output (GPIO) pins, are disabled and released during the driver unbind process. This improper resource management could lead to system instability or resource exhaustion, potentially resulting in a Denial of Service (DoS).
