Overview

About vulnerability

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 flaw was found in the Linux kernel, specifically within the spi: imx driver. This vulnerability, known as a use-after-free, occurs when the system attempts to access memory that has already been released, leading to unpredictable behavior. A local attacker could potentially exploit this issue to cause the system to crash, resulting in a denial of service, or in some cases, gain elevated privileges.
