  3. CVE-2025-21711
In the Linux kernel, the following vulnerability has been resolved: net/rose: prevent integer overflows in rose_setsockopt() In case of possible unpredictably large arguments passed to rose_setsockopt() and multiplied by extra values on top of that, integer overflows may occur. Do the safest minimum and fix these issues by checking the contents of 'opt' and returning -EINVAL if they are too large. Also, switch to unsigned int and remove useless check for negative 'opt' in ROSE_IDLE case.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/rose: evitar desbordamientos de números enteros en rose_setsockopt() En caso de que se pasen argumentos impredeciblemente grandes a rose_setsockopt() y se multipliquen por valores adicionales además de eso, pueden ocurrir desbordamientos de números enteros. Haga lo mínimo más seguro y solucione estos problemas comprobando el contenido de 'opt' y devolviendo -EINVAL si es demasiado grande. Además, cambie a int sin signo y elimine la comprobación inútil para 'opt' negativo en el caso de ROSE_IDLE.
