CVE-2026-64407

CVE-2026-64407 concerns the Linux kernel Bluetooth driver btnxpuart. The vulnerability arises during the v3 firmware download: a controller can request firmware with a 32‑bit offset and 16‑bit length, and nxp_recv_fw_req_v3() only validates the lower bound. It computes an offset and uses it to re...
