CVE-2026-80854

CVE-2026-80854 affects the Linux kernel USB gadget f_tcm (TCM backend) driver. The root cause is a race condition : usbg_port_unlink() decrements tpg_port_count in the fabric_pre_unlink() callback, before core_dev_del_lun() finishes draining active se_lun references. If the last-LUN unlink overla...
