CVE-2026-46226 Details
Description
In the Linux kernel, the following vulnerability has been resolved: spi: fsl: fix controller deregistration Make sure to deregister the controller before releasing underlying resources like DMA during driver unbind.
A vulnerability exists in the Linux kernel's SPI (Serial Peripheral Interface) subsystem, specifically within the Freescale (FSL) SPI controller driver. The issue arises because the driver fails to properly deregister the SPI controller before releasing associated resources, such as Direct Memory Access (DMA), during the unbinding process. This flaw can potentially lead to resource leaks or undefined behavior.
Users can apply the latest patches from the Linux kernel stable tree to address this vulnerability. The patches are available in the Linux Git repository under the stable branch.
