Descriptions

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

vdpa: solidrun: Fix UB bug with devres

In psnet_open_pf_bar() and snet_open_vf_bar() a string later passed to
pcim_iomap_regions() is placed on the stack. Neither
pcim_iomap_regions() nor the functions it calls copy that string.

Should the string later ever be used, this, consequently, causes
undefined behavior since the stack frame will by then have disappeared.

Fix the bug by allocating the strings on the heap through
devm_kasprintf().

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vdpa: solidrun: Fix UB bug with devres En psnet_open_pf_bar() y snet_open_vf_bar(), una cadena que luego se pasa a pcim_iomap_regions() se coloca en la pila. Ni pcim_iomap_regions() ni las funciones que llama copian esa cadena. Si la cadena se utiliza más tarde, esto, en consecuencia, provoca un comportamiento indefinido ya que el marco de la pila habrá desaparecido para entonces. Corrija el error asignando las cadenas en el montón a través de devm_kasprintf().
