kernel: scsi: core: Wake up the error handler when final completions race against each other

Race condition vulnerabilities were found in the Linux kernel's SCSI error handler wake-up logic. Memory ordering issues in scsidechostbusy and ordering problems in scsiehinchostfailed can cause the SCSI error handler to never wake up when command completions race against each other. This leaves...

CVE-2026-72088

The CVE-2026-72088 entry concerns the Linux kernel SCSI HPSA driver IOACCEL2 reset path. The root cause was a DMA mapping leak when phys_disk->in_reset is set, causing an early return without cleaning up resources allocated for the command. The fix adds proper error cleanup: unmapping the IOAC...

CVE-2026-72087

CVE-2026-72087 affects the Linux kernel SCSI LPFC driver, specifically the lpfc_sli4_driver_resource_setup() path. The vulnerability is a memory leak: memory allocated for mboxq via mempool_alloc() is not freed in some early exit error paths. The cited fixes relocate mempool_free() to an earlier ...

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...
