CVE-2026-80870

CVE-2026-80870 affects the Linux kernel component drm/amdkfd (AMD Kernel Fusion Driver). The vulnerability exists in the CRIU restore flow, where userspace-provided object IDs are passed to idr_alloc() without validation in kfd_criu_restore_event() and criu_restore_memory_of_gpu() . If a restored...

CVE-2026-80788

CVE-2026-80788 affects the Linux kernel NVMe-over-TCP target subsystem (nvmet-tcp ). A remote NVMe initiator can send a command with an oversized SGL (Scatter Gather List) field, causing nvmet_tcp_map_data() to allocate over one million scatterlist/iovec entries. This exceeds MAX_PAGE_ORDER , tri...
