Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: mana: Guard mana_remove against double invocation<br />
<br />
If PM resume fails (e.g., mana_attach() returns an error), mana_probe()<br />
calls mana_remove(), which tears down the device and sets<br />
gd->gdma_context = NULL and gd->driver_data = NULL.<br />
<br />
However, a failed resume callback does not automatically unbind the<br />
driver. When the device is eventually unbound, mana_remove() is invoked<br />
a second time. Without a NULL check, it dereferences gc->dev with<br />
gc == NULL, causing a kernel panic.<br />
<br />
Add an early return if gdma_context or driver_data is NULL so the second<br />
invocation is harmless. Move the dev = gc->dev assignment after the<br />
guard so it cannot dereference NULL.
