Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the powerpc/powernv/sriov component where a pointer dereference occurs before a null check on the
iov pointer. This can lead to null pointer dereference errors. The issue was detected using cppcheck static analysis in the file linux/arch/powerpc/platforms/powernv/pci-sriov.c at line 597. The vulnerable code attempts to access iov->num vfs without first verifying that iov is not null.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
