CVE-2026-72085

CVE-2026-72085 concerns the Linux kernel SCSI xen scsiback path. A path in scsiback_get_pend_req() creates a pending command with an uninitialized or not-yet-kref’d se_cmd; if a submission is aborted via a bad grant or unknown ring_req.act, transport_generic_free_cmd() underflows the reference co...

CVE-2026-72084

The CVE-2026-72084 vulnerability affects the Linux kernel SCSI subsystem: PR-OUT TransportID parsing for iSCSI can over-read when the provided buffer length isn’t properly validated, potentially allowing out-of-bounds reads. The fix introduces length checks on the iSCSI TransportID (ADDITIONAL LE...

CVE-2026-72083

CVE-2026-72083 affects the Linux kernel SCSI target core code. The vulnerability (iSCSI ISID use-after-free in REGISTER AND MOVE) arises when core_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT parameter list with transport_kmap_data_sg(), parses the iSCSI TransportID, and ...

CVE-2026-72082

The CVE concerns the Linux kernel SCSI elx/efct path. When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path returns -ENOSPC without releasing the reference obtained via kref_get_unless_zero(), causing a permanent reference leak on the io_to_abort object. Additionally, the abort_...
