In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: hda: Fix UAF when reloading module
hda_generic_machine_select() appends -idisp to the tplg filename by
allocating a new string with devm_kasprintf(), then stores the string
right back into the global variable snd_soc_acpi_intel_hda_machines.
When the module is unloaded, this memory is freed, resulting in a global
variable pointing to freed memory. Reloading the module then triggers
a use-after-free:

Fix it by copying the match array with devm_kmemdup_array() before we
modify it.
