CVE-2024-46711

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-46711
In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: fix ID 0 endp usage after multiple re-creations 'local_addr_used' and 'add_addr_accepted' are decremented for addresses not related to the initial subflow (ID0), because the source and destination addresses of the initial subflows are known from the beginning: they don't count as "additional local address being used" or "ADD_ADDR being accepted". It is then required not to increment them when the entrypoint used by the initial subflow is removed and re-added during a connection. Without this modification, this entrypoint cannot be removed and re-added more than once.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mptcp: pm: se corrige el uso de ID 0 endp después de múltiples recreaciones. 'local_addr_used' y 'add_addr_accepted' se decrementan para direcciones no relacionadas con el subflujo inicial (ID0), porque las direcciones de origen y destino de los subflujos iniciales se conocen desde el principio: no cuentan como "dirección local adicional en uso" o "ADD_ADDR aceptada". Luego, se requiere no incrementarlas cuando el punto de entrada utilizado por el subflujo inicial se elimina y se vuelve a agregar durante una conexión. Sin esta modificación, este punto de entrada no se puede eliminar y volver a agregar más de una vez.
