CVE-2026-45996 Details
Description
In the Linux kernel, the following vulnerability has been resolved: spi: imx: fix use-after-free on unbind The SPI subsystem frees the controller and any subsystem allocated driver data as part of deregistration (unless the allocation is device managed). Take another reference before deregistering the controller so that the driver data is not freed until the driver is done with it.
A use-after-free vulnerability has been identified in the SPI IMX controller within the Linux kernel. This issue arises during the unbinding process, where the SPI subsystem deregisters the controller and frees any associated driver data. If the data is not device-managed, it can lead to premature deallocation. The vulnerability can be exploited by taking an additional reference to the controller before deregistration, ensuring that the driver data remains available until it is no longer needed.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
