  3. CVE-2023-52754
In the Linux kernel, the following vulnerability has been resolved: media: imon: fix access to invalid resource for the second interface imon driver probes two USB interfaces, and at the probe of the second interface, the driver assumes blindly that the first interface got bound with the same imon driver. It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver accesses the data from drvdata as struct imon_context object although it's a completely different one that was assigned by another driver. This patch adds a sanity check -- whether the first interface is really bound with the imon driver or not -- for avoiding the problem above at the probe time.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: medios: imon: corrige el acceso a un recurso no válido para la segunda interfaz. El controlador imon prueba dos interfaces USB y, en la prueba de la segunda interfaz, el controlador asume ciegamente que la primera interfaz obtuvo atado con el mismo conductor imon. Generalmente es cierto, pero aún es posible que la primera interfaz esté vinculada con otro controlador a través de un descriptor con formato incorrecto. Entonces puede provocar una corrupción de la memoria, como descubrió syzkaller; El controlador imon accede a los datos de drvdata como objeto struct imon_context aunque es uno completamente diferente asignado por otro controlador. Este parche agrega una verificación de cordura (si la primera interfaz está realmente vinculada con el controlador imon o no) para evitar el problema anterior en el momento de la prueba.
