CVE-2026-74617

CVE-2026-74617 affects the Linux kernel 's dibs device driver. The root cause is that dibs->lock was initialised in dibs_dev_add(), but a dibs device can already receive interrupts before that call: ism_probe() invokes ism_dev_init() (which calls request_irq()) prior to dibs_dev_add(). A GID e...

CVE-2026-74616

CVE-2026-74616 affects the Linux kernel XDP (eXpress Data Path) subsystem. The flaw resides in xdpf_clone(), which clones broadcast copies into a single page and sets frame_sz to PAGE_SIZE. The existing size check only validates that the linear xdp_frame header, headroom, and packet data do not e...

CVE-2026-74615

CVE-2026-74615 is a slab-use-after-free in the Linux kernel vxlan module. The root cause is that vxlan_changelink() arms the FDB ageing timer without a netif_running() check, so on a never-brought-up device the timer persists after free_netdev() releases the vxlan_dev struct, causing the timer co...

CVE-2026-74613

CVE-2026-74613 is a use-after-free in the Linux kernel's vsock/virtio transport (net/vmw_vsock/virtio_transport.c). A prior commit (b917507e5ad9) made the RX worker jump to a common exit path when rx_run is clear, but that path still refills the RX queue when the buffer count is low. Work queued ...
