CVE-2026-72302 in Linux
Resumen
por MITRE • 2026-08-15
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.
