CVE-2026-68368

The CVE concerns the Linux kernel USB gadget driver f_ncm (ncm_unwrap_ntb). The issue: when unpacking host-supplied NTBs, the code checked datagram length against frame_max but did not ensure the datagram fits within the declared block length, and subsequent NTBs from a single socket buffer were ...

CVE-2026-68087

CVE-2026-68087 affects the Linux kernel HID wacom driver. The vulnerability stems from using GFP_KERNEL inside wacom_wac_queue_flush(), which is invoked from the atomic-context, URB-completion path (hid_irq_in()) via wacom_raw_event → wacom_wac_pen_serial_enforce → wacom_wac_queue_flush. Using GF...
