The function\nthen calls of_node_put(node) before checking whether\nsyscon_regmap_lookup_by_phandle() returns an error. If an error occurs,\ndev_err_probe() dereferences the node pointer to print diagnostic\ninformation, but the node memory may have already been freed due to the\nearlier of_node_put(), leading to a use-after-free vulnerability.\n\nFix this by moving the of_node_put() call after the error check, ensuring\nthe node is still valid when accessed in the error path.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
