If add_setting() returns -EPROBE_DEFER, create_pinctrl()\ncalls pinctrl_free(). However, pinctrl_free() attempts to acquire\npinctrl_maps_mutex, which is already held by create_pinctrl(), leading to\na potential deadlock.\n\nThis patch resolves the issue by releasing pinctrl_maps_mutex before\ncalling pinctrl_free(), preventing the deadlock.\n\nThis bug was discovered and resolved using Coverity Static Analysis\nSecurity Testing (SAST) by Synopsys, Inc."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pinctrl: soluciona el punto muerto en create_pinctrl() al manejar -EPROBE_DEFER En create_pinctrl(), pinctrl_maps_mutex se adquiere antes de llamar a add_setting(). Si add_setting() devuelve -EPROBE_DEFER, create_pinctrl() llama a pinctrl_free(). Sin embargo, pinctrl_free() intenta adquirir pinctrl_maps_mutex, que ya est\u00e1 en manos de create_pinctrl(), lo que lleva a un posible punto muerto. Este parche resuelve el problema liberando pinctrl_maps_mutex antes de llamar a pinctrl_free(), evitando el punto muerto.
