CVE-2026-89936

A flaw was found in the Linux kernel's iio: dac: m62332 driver. The m62332_set_value() function incorrectly manages the reference count for the Vcc regulator. When a channel's value is changed directly from one non-zero value to another, the regulator is enabled multiple times, but only disabled once when the value returns to zero. This imbalance causes the regulator to remain enabled indefinitely, leading to a resource leak.
