CVE-2026-80789 nvmet-tcp: bound SGL data length before allocating command buffers

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: bound SGL data length before allocating command buffers nvmettcpmapdata reads the host-controlled 32-bit sgl-length and, for the in-capsule offset descriptor type 0x01, checks it against port-inlinedatasize before use...

CVE-2026-80789

In the Linux kernel nvmet-tcp component (NVMe/TCP target), a host-controlled 32-bit sgl->length field is only validated for in-capsule SGL descriptors. Non-inline transport SGL data-block descriptors—those used for out-of-capsule writes—skip the check entirely, causing an unbounded sgl_alloc()...

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...

CVE-2026-80787

CVE-2026-80787 is a use-after-free in the Linux kernel's nvmet_pci_epf module (NVMe Target over PCI Endpoint Function). After submitting an I/O command via req->execute(), the function nvmet_pci_epf_exec_iod_work() reads iod->data_len and iod->dma_dir to decide whether to wait for comple...

CVE-2026-80786

CVE-2026-80786 affects the Linux kernel fbdev (framebuffer) subsystem. The root cause is that user-invoked calls to fb_set_var() from sysfs and driver code paths were missing fbcon -related steps (checking mode-change feasibility, updating hardware state, and updating fbcon). Only the FBIOPUT_VSC...
