Background
The powerpc/fsl_rio package is a component of the Linux Kernel that provides support for Freescale RapidIO (RIO) devices on PowerPC architecture. RapidIO is a high-performance interconnect technology used in embedded systems. The fsl_rio_setup function in this package is responsible for setting up the RIO subsystem. However, a refcount leak vulnerability has been discovered in this function.
Vulnerability Detail
The refcount leak vulnerability in fsl_rio_setup allows an attacker to cause a reference count leak, leading to a use-after-free condition. By repeatedly calling the fsl_rio_setup function without properly releasing the references, an attacker can exhaust the available memory and potentially execute arbitrary code or crash the system. This vulnerability was introduced in version v3.3 of the Linux Kernel and has been fixed in version v5.10.121.
How To Fix
No fixed version is published for this vulnerability.
