In the Linux kernel, the following vulnerability has been resolved: usb: gadget: composite: fix dead empty check in the USB_DT_OTG handler The OTG… (CVE-2026-64347)CVE-2026-64347 0 A vulnerability in the Linux kernel's USB gadget composite driver was resolved by fixing a dead check in the USB_DT_OTG handler. The issue arises because list_first_entry() never returns NULL, causing a check for an empty configuration list to be ineffective. This can lead to reading invalid memory and copying unintended data during USB control transfers when no configuration is set. The flaw can occur during gadget teardown races or when a driver sets OTG status before adding a configuration. The fix replaces list_first_entry() with list_first_entry_or_null() to properly detect an empty list and avoid invalid memory access.
