CVE-2026-64406

CVE-2026-64406 affects the Linux kernel Bluetooth subsystem. Multiple vendors report a use-after-free in bt_accept_dequeue() where a temporary reference to the accept queue is dropped too early, causing sock_hold() to access freed memory during listening L2CAP socket cleanup. The fix retains the ...

CVE-2026-64376

CVE-2026-64376 affects the Linux kernel firmware_loader: in firmware_upload_register(), after fw_create_instance() succeeds, a failure path frees fw_sysfs without balancing the embedded device reference, risking a refcount leak of the embedded struct device. The recommended fix is to use put_devi...
