    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nof: unittest: fix use-after-free in of_unittest_changeset()\n\nThe 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.\n\nFix this by moving the of_node_put() call after the last access to\n'parent', avoiding the UAF.",
