CVE-2024-27021

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-27021
In the Linux kernel, the following vulnerability has been resolved: r8169: fix LED-related deadlock on module removal Binding devm_led_classdev_register() to the netdev is problematic because on module removal we get a RTNL-related deadlock. Fix this by avoiding the device-managed LED functions. Note: We can safely call led_classdev_unregister() for a LED even if registering it failed, because led_classdev_unregister() detects this and is a no-op in this case.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: r8169: corrige el punto muerto relacionado con el LED al eliminar el módulo. Vincular devm_led_classdev_register() al netdev es problemático porque al eliminar el módulo obtenemos un punto muerto relacionado con RTNL. Solucione este problema evitando las funciones LED administradas por el dispositivo. Nota: Podemos llamar con seguridad a led_classdev_unregister() para un LED incluso si falla el registro, porque led_classdev_unregister() detecta esto y no es operativo en este caso.
