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

IORING REGISTER PBUF RING function can reuse an old struct io buffer list if it was created for a legacy selected buffer and has been emptied. This violates the requirement that most of the field should remain stable after publication.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
