ASoC: SOF: ipc3-control: Use overflow checks in control_update size calc<\/p>\n
In sof_ipc3_control_update(), the expected_size calculation uses
\nfirmware-provided cdata->num_elems in arithmetic that could overflow
\non 32-bit platforms, wrapping to a small value. This would allow the
\ncdata->rhdr.hdr.size comparison to pass with mismatched sizes,
\npotentially leading to out-of-bounds access in snd_sof_update_control.<\/p>\n
Use check_mul_overflow() and check_add_overflow() to detect and reject
\noverflowed size calculations.<\/p>\n","protected":false},"excerpt":{"rendered":"
