  3. CVE-2023-53097
In the Linux kernel, the following vulnerability has been resolved: powerpc/iommu: 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: powerpc/iommu: se corrige una fuga de memoria con debugfs_lookup(). Al llamar a debugfs_lookup(), se debe ejecutar dput() en el resultado; de lo contrario, la fuga de memoria se producirá con el tiempo. Para simplificar, simplemente llame a debugfs_lookup_and_remove(), que gestiona toda la lógica a la vez.
