Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw within the pci endpoint test module. A commit introduced a change that allows for a potential array underflow in the pci endpoint test bar() function when a negative number is passed through the pci endpoint test ioctl() function.
