Description

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

scsi: aacraid: Fix double-free on probe failure

aac_probe_one() calls hardware-specific init functions through the
aac_driver_ident::init pointer, all of which eventually call down to
aac_init_adapter().

If aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member.

After the hardware-specific init function returns an error,
aac_probe_one() goes down an error path that frees the memory pointed to
by aac_dev::queues, resulting.in a double-free.
