USN-4694-1: Linux kernel vulnerability
First published: Thu Jan 14 2021(Updated: )
It was discovered that the LIO SCSI target implementation in the Linux kernel performed insufficient identifier checking in certain XCOPY requests. An attacker with access to at least one LUN in a multiple backstore environment could use this to expose sensitive information or modify data.
