Details

In the Linux kernel, the following vulnerability has been resolved: ata: libata-core: fix NULL pointer deref in atahostallocpinfo() In an unlikely (and probably wrong?) case that the 'ppi' parameter of atahostallocpinfo() 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 '&atadummyport_info' to fix the possible kernel oops for good... Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.
