CVE-2026-72086
A flaw was found in the Linux kernel's scsi: xen: scsiback component. A pvSCSI guest can trigger a resource leak by issuing specific SCSI Small Computer System Interface requests when a task management operation fails. This vulnerability allows the guest to leak command tags associated with a...
CVE-2026-72085
A flaw was found in the Linux kernel's scsi: xen: scsiback component. This vulnerability allows a malicious virtualized SCSI pvSCSI guest to trigger a reference count underflow by sending specially crafted requests. This can lead to a denial of service, potentially stopping a Logical Unit Number...
