  3. CVE-2024-53063
In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: prevent the risk of out of memory access The dvbdev contains a static variable used to store dvb minors. The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set or not. When not set, dvb_register_device() won't check for boundaries, as it will rely that a previous call to dvb_register_adapter() would already be enforcing it. On a similar way, dvb_device_open() uses the assumption that the register functions already did the needed checks. This can be fragile if some device ends using different calls. This also generate warnings on static check analysers like Coverity. So, add explicit guards to prevent potential risk of OOM issues.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: dvbdev: evitar el riesgo de acceso fuera de memoria El dvbdev contiene una variable estática utilizada para almacenar dvb minors. El comportamiento de la misma depende de si CONFIG_DVB_DYNAMIC_MINORS está configurado o no. Cuando no está configurado, dvb_register_device() no comprobará los límites, ya que dependerá de que una llamada anterior a dvb_register_adapter() ya lo estaría aplicando. De forma similar, dvb_device_open() utiliza la suposición de que las funciones de registro ya realizaron las comprobaciones necesarias. Esto puede ser frágil si algún dispositivo termina utilizando llamadas diferentes. Esto también genera advertencias en los analizadores de comprobaciones estáticas como Coverity. Por lo tanto, agregue protecciones explícitas para evitar el riesgo potencial de problemas de OOM.
