Title: kernel de Linux
Description: En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: PCI: Evite posibles lecturas fuera de los límites en pci_dev_for_each_resource() Coverity se queja de que el puntero en pci_dev_for_each_resource() puede ser incorrecto, es decir, podría usarse para lecturas fuera de los límites. No hay ningún problema real en este momento porque tenemos otra verificación posterior y no se está realizando la lectura fuera de los límites. En cualquier caso, es mejor que el código tenga esto solucionado, de ahí el cambio propuesto. Como señaló Jonas, "probablemente hace que el código tenga un rendimiento un poco menor, ya que ahora se verificará que res no sea NULL (lo que siempre será cierto), pero dudo que sea significativo (o en alguna ruta activa)".

In the Linux kernel, the following vulnerability has been resolved:

PCI: Avoid potential out-of-bounds read in pci_dev_for_each_resource()

Coverity complains that pointer in the pci_dev_for_each_resource() may be
wrong, i.e., might be used for the out-of-bounds read.

There is no actual issue right now because we have another check afterwards
and the out-of-bounds read is not being performed. In any case it's better
code with this fixed, hence the proposed change.

As Jonas pointed out "It probably makes the code slightly less performant
as res will now be checked for being not NULL (which will always be true),
but I doubt it will be significant (or in any hot paths)."

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
