*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
regulator: core: fix unbalanced of node refcount in regulator_dev_lookup()<br />
<br />
I got the the following report:<br />
<br />
OF: ERROR: memory leak, expected refcount 1 instead of 2,<br />
of_node_get()/of_node_put() unbalanced - destroy cset entry:<br />
attach overlay node /i2c/pmic@62/regulators/exten<br />
<br />
In of_get_regulator(), the node is returned from of_parse_phandle()<br />
with refcount incremented, after using it, of_node_put() need be called.
