In the Linux kernel, the following vulnerability has been resolved: safesetid: check size of policy writes syzbot attempts to write a buffer with a large size to a sysfs entry with writes handled by handle_policy_update(), triggering a warning in kmalloc. Check the size specified for write buffers before allocating. [PM: subject tweak]
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: safesetid: comprobar el tamaño de las escrituras de políticas syzbot intenta escribir un búfer de gran tamaño en una entrada sysfs con escrituras gestionadas por handle_policy_update(), lo que activa una advertencia en kmalloc. Compruebe el tamaño especificado para los búferes de escritura antes de asignar. [MP: modificación del asunto]
