  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: single: fix refcount leak in pcs_add_gpio_func()\n\nof_parse_phandle_with_args() returns a device_node pointer with refcount\nincremented in gpiospec.np. The loop iterates through all phandles but\nnever releases the reference, causing a refcount leak on each iteration.\n\nAdd of_node_put() calls to release the reference after extracting the\nneeded arguments and on the error path when devm_kzalloc() fails.\n\nThis bug was detected by our static analysis tool and verified by my\ncode review.",
