Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the rapidio/tsi721 component where a bad dereference can occur in the tsi721 db dpc() function. This happens because a list for each() loop may exit with the dbell iterator pointing to invalid memory if the searched item is not found. Additionally, the found variable is not reset at the start of each iteration, causing subsequent items to be incorrectly marked as found after the first successful match.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
