A memory leak in the sof_set_get_large_ctrl_data() function in
sound/soc/sof/ipc.c in the Linux kernel through 5.3.9 allows attackers to
cause a denial of service (memory consumption) by triggering
sof_get_ctrl_copy_params() failures, aka CID-45c1380358b1.

It was discovered that the Sound Open Firmware (SOF) driver in the Linux
kernel did not properly deallocate memory in certain error conditions. A
local attacker could use this to cause a denial of service (kernel memory
exhaustion).
