In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove()
In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to
fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in
fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io
triggers KASAN use-after-free. To avoid the use-after-free, keep the
reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to
fsl_destroy_mc_io().
This patch needs rework to apply to kernels older than v5.15.
