Descriptions
In the Linux kernel, the following vulnerability has been resolved:
pstore: inode: Only d_invalidate() is needed
Unloading a modular pstore backend with records in pstorefs would
trigger the dput() double-drop warning:
WARNING: CPU: 0 PID: 2569 at fs/dcache.c:762 dput.part.0+0x3f3/0x410
Using the combo of d_drop()/dput() (as mentioned in
Documentation/filesystems/vfs.rst) isn't the right approach here, and
leads to the reference counting problem seen above. Use d_invalidate()
and update the code to not bother checking for error codes that can
never happen.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pstore: inode: solo se necesita d_invalidate(). La descarga de un backend modular de pstore con registros en pstorefs activaría la advertencia de doble caída de dput(): ADVERTENCIA: CPU: 0 PID: 2569 en fs/dcache.c:762 dput.part.0+0x3f3/0x410 Usar la combinación de d_drop()/dput() (como se menciona en Documentation/filesystems/vfs.rst) no es el enfoque correcto aquí, y conduce al problema de recuento de referencias visto anteriormente. Utilice d_invalidate() y actualice el código para no molestarse en buscar códigos de error que nunca sucederán. ---
