  "description": "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-\u003Eroot_mc_bus_dev-\u003Emc_io is passed to fsl_destroy_mc_io(). However, mc-\u003Eroot_mc_bus_dev is already freed in fsl_mc_device_remove(). Then reference to mc-\u003Eroot_mc_bus_dev-\u003Emc_io triggers KASAN use-after-free. To avoid the use-after-free, keep the reference to mc-\u003Eroot_mc_bus_dev-\u003Emc_io in a local variable and pass to fsl_destroy_mc_io().  This patch needs rework to apply to kernels older than v5.15.",
