CVE-2024-36947

  3. CVE-2024-36947
In the Linux kernel, the following vulnerability has been resolved: qibfs: fix dentry leak simple_recursive_removal() drops the pinning references to all positives in subtree. For the cases when its argument has been kept alive by the pinning alone that's exactly the right thing to do, but here the argument comes from dcache lookup, that needs to be balanced by explicit dput().

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: qibfs: arreglar la fuga de dentry simple_recursive_removal() elimina las referencias de fijación a todos los positivos en el subárbol. Para los casos en los que su argumento se ha mantenido vivo solo mediante la fijación, eso es exactamente lo correcto, pero aquí el argumento proviene de la búsqueda de dcache, que debe equilibrarse con dput() explícito.
