In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: ipc3-control: Use overflow checks in control_update size calc

In sof_ipc3_control_update(), the expected_size calculation uses

firmware-provided cdata->num_elems in arithmetic that could overflow

on 32-bit platforms, wrapping to a small value. This would allow the

cdata->rhdr.hdr.size comparison to pass with mismatched sizes,

potentially leading to out-of-bounds access in snd_sof_update_control.

Use check_mul_overflow() and check_add_overflow() to detect and reject

overflowed size calculations. (NVD)
