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.
