CVE-2024-42090

  3. CVE-2024-42090
In the Linux kernel, the following vulnerability has been resolved: pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER In create_pinctrl(), pinctrl_maps_mutex is acquired before calling add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl() calls pinctrl_free(). However, pinctrl_free() attempts to acquire pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to a potential deadlock. This patch resolves the issue by releasing pinctrl_maps_mutex before calling pinctrl_free(), preventing the deadlock. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.

Summary
  • (es) 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 está 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. Este error fue descubierto y resuelto utilizando Coverity Static Analysis Security Testing (SAST) por Synopsys, Inc.
