  3. CVE-2023-52936
In the Linux kernel, the following vulnerability has been resolved: kernel/irq/irqdomain.c: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: kernel/irq/irqdomain.c: se corrige la pérdida de memoria mediante el uso de debugfs_lookup(). Al llamar a debugfs_lookup(), se debe ejecutar dput() en el resultado; de lo contrario, la pérdida de memoria se producirá con el tiempo. Para simplificar, simplemente llame a debugfs_lookup_and_remove(), que gestiona toda la lógica a la vez.
