  3. CVE-2022-49451
In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Fix list protocols enumeration in the base protocol While enumerating protocols implemented by the SCMI platform using BASE_DISCOVER_LIST_PROTOCOLS, the number of returned protocols is currently validated in an improper way since the check employs a sum between unsigned integers that could overflow and cause the check itself to be silently bypassed if the returned value 'loop_num_ret' is big enough. Fix the validation avoiding the addition.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firmware: arm_scmi: Se corrige la enumeración de protocolos de lista en el protocolo base Al enumerar protocolos implementados por la plataforma SCMI utilizando BASE_DISCOVER_LIST_PROTOCOLS, la cantidad de protocolos devueltos actualmente se valida de manera incorrecta ya que la verificación emplea una suma entre números enteros sin signo que podría desbordarse y hacer que la verificación en sí se omita silenciosamente si el valor devuelto 'loop_num_ret' es lo suficientemente grande. Arregle la validación evitando la suma.
