Description OSIDB Bzimport 2026-08-15 06:11:18 UTC
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.
