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

ALSA: hda/ca0132: fixup buffer overrun at tuning_ctl_set()

tuning_ctl_set() might have buffer overrun at (X) if it didn't break
from loop by matching (A).

static int tuning_ctl_set(...)
{
for (i = 0; i < TUNING_CTLS_COUNT; i++)
(A) if (nid == ca0132_tuning_ctls[i].nid)
break;

snd_hda_power_up(...);
(X) dspio_set_param(..., ca0132_tuning_ctls[i].mid, ...);
snd_hda_power_down(...); ^

return 1;
}

We will get below error by cppcheck

sound/pci/hda/patch_ca0132.c:4229:2: note: After for loop, i has value 12
for (i = 0; i < TUNING_CTLS_COUNT; i++)
