- Summary
- regulator: core: fix unbalanced of node refcount in regulator_dev_lookup()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
regulator: core: fix unbalanced of node refcount in regulatordevlookup()
I got the the following report:
OF: ERROR: memory leak, expected refcount 1 instead of 2, ofnodeget()/ofnodeput() unbalanced - destroy cset entry: attach overlay node /i2c/pmic@62/regulators/exten
In ofgetregulator(), the node is returned from ofparsephandle() with refcount incremented, after using it, ofnodeput() need be called.
