CVE-2026-74702

CVE-2026-74702 affects the vhost-scsi component of the Linux kernel. The root cause is that vhost_scsi_setup_vq_cmds() allocates the protection scatterlist array (prot_sgl) based on the VIRTIO_SCSI_F_T10_PI feature bit at endpoint setup, but command pools are not rebuilt when VHOST_SET_FEATURES l...
