CVE-2026-68449
The CVE-2026-68449 issue affects the Linux kernel in the sata_dwc_460ex NCQ tag completion path. A hand-rolled bit-scanning loop could loop infinitely when tag_mask contains only high bits (e.g., 0x80000000); the inner loop shifts until overflow to 0, causing an infinite loop in hardirq context w...

CVE-2026-45855
A flaw was found in the Linux kernel's libata-scsi component. This vulnerability allows for a denial of service DoS where non-Native Command Queuing NCQ commands can experience significant delays or complete starvation. This occurs when non-NCQ commands are issued while NCQ commands are actively...
CVE-2026-45855 ata: libata-scsi: avoid Non-NCQ command starvation
In the Linux kernel, the following vulnerability has been resolved: ata: libata-scsi: avoid Non-NCQ command starvation When a non-NCQ command is issued while NCQ commands are being executed, atascsiqcissue indicates to the SCSI layer that the command issuing should be deferred by returning...
Denial Of Service (DoS)
qemu-kvm-rhev is vulnerable to denial of service DoS attacks. The vulnerability exists as a use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service instance crash or possibly execute arbitrary code via a...
CVE-2016-1568
CVE-2016-1568 is a use-after-free in QEMU’s AHCI emulation (hw/ide/ahci.c) when IDE AHCI Emulation is enabled. A guest user can cause a denial of service (QEMU process crash) and potentially execute arbitrary code via an invalid AHCI NCQ AIO command. The issue is triggered by use-after-free in NC...
