CVE-2023-53788
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++)
^
sound/pci/hda/patch_ca0132.c:4234:43: note: Array index out of bounds
dspio_set_param(codec, ca0132_tuning_ctls[i].mid, 0x20,
^
This patch cares non match case.
