Descriptions
In the Linux kernel, the following vulnerability has been resolved: sched/debug: fix dentry leak in update_sched_domain_debugfs Kuyo reports that the pattern of using debugfs_remove(debugfs_lookup())
leaks a dentry and with a hotplug stress test, the machine eventually
runs out of memory. Fix this up by using the newly created debugfs_lookup_and_remove() call
instead which properly handles the dentry reference counting logic.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sched/debug: corrige la fuga de dentry en update_sched_domain_debugfs Kuyo informa que el patrón de uso de debugfs_remove(debugfs_lookup()) pierde un dentry y con una prueba de estrés de conexión en caliente, la máquina eventualmente se queda sin memoria. Solucione este problema utilizando la llamada debugfs_lookup_and_remove() recién creada, que maneja adecuadamente la lógica de conteo de referencias de dentry.
