CVE-2026-74703

A flaw was found in the Linux kernel's vhost-scsi component. When T10 Protection Information PI is negotiated, a remote attacker could send a specially crafted request with malformed scatterlist counts. This could lead to an invalid memory allocation operation, triggering a kernel panic and...

qemu-kvm: Heap buffer overflow in virtio-blk SCSI request handling

A flaw was found in QEMU's virtio-blk device. The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed virtio-blk SCSI request, leading to an...

CVE-2026-74702

CVE-2026-74702 affects the Linux kernel vhost-scsi module. The root cause is that vhost_scsi_set_features() accepts changes to virtio feature bits (specifically VIRTIO_SCSI_F_T10_PI) after the endpoint is already active via VHOST_SCSI_SET_ENDPOINT. This leaves the prot_sgl scatterlist array as NU...
