In the Linux kernel, the following vulnerability has been resolved:
ata: libata-core: fix NULL pointer deref in ata_host_alloc_pinfo()
In an unlikely (and probably wrong?) case that the 'ppi' parameter of
ata_host_alloc_pinfo() points to an array starting with a NULL pointer,
there's going to be a kernel oops as the 'pi' local variable won't get
reassigned from the initial value of NULL. Initialize 'pi' instead to
'&ata_dummy_port_info' to fix the possible kernel oops for good...
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
An official patch is available. Apply the patch as soon as possible.
