Linux FSL MC Bus Component DoS

The vulnerability of the drivers/bus/fsl-mc/fsl-mc-bus.c component in the Linux operating system is related to the use of memory after it has been freed. Exploiting this vulnerability can allow an attacker to cause a service failure...

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 driveroverride field without proper locking. This can lead to system instability or potentially allow an attacker to...
