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

Description A memory leak issue has been identified in the Linux kernel, specifically in the ibmvnic module. The problem arises from the logic introduced in a particular commit, which causes a 32-byte memory leak whenever the last rwi in the list is processed successfully.
