CVE-2026-23087

EUVD-2026-5455
In the Linux kernel, the following vulnerability has been resolved:

scsi: xen: scsiback: Fix potential memory leak in scsiback_remove()

Memory allocated for struct vscsiblk_info in scsiback_probe() is not
freed in scsiback_remove() leading to potential memory leaks on remove,
as well as in the scsiback_probe() error paths. Fix that by freeing it
in scsiback_remove().
