CVE-2026-53115

A flaw was found in the Linux kernel's fsl-mc bus driver. During the driver probing process, a Use-After-Free (UAF) vulnerability can occur because the match() callback accesses the driver_override field without proper locking. This can lead to system instability or potentially allow an attacker to execute arbitrary code.

This vulnerability is rated Moderate because exploitation requires local access and is constrained to systems utilizing the Freescale Management Complex (fsl-mc) bus architecture. On typical Red Hat Enterprise Linux and Red Hat In-Vehicle OS deployments lacking this specialized NXP hardware, the affected bus driver is not exercised. Furthermore, triggering the race condition during device probing requires local administrative interaction with driver override settings, substantially limiting practical impact.
