of: unittest: fix use-after-free in of_unittest_changeset()<\/p>\n
The variable ‘parent’ is assigned the value of ‘nchangeset’ earlier in the
\nfunction, meaning both point to the same struct device_node. The call to
\nof_node_put(nchangeset) can decrement the reference count to zero and
\nfree the node if there are no other holders. After that, the code still
\nuses ‘parent’ to check for the presence of a property and to read a
\nstring property, leading to a use-after-free.<\/p>\n
Fix this by moving the of_node_put() call after the last access to
\n‘parent’, avoiding the UAF.<\/p>\n","protected":false},"excerpt":{"rendered":"
