CVE-2026-64339

CVE-2026-64339 is an out-of-bounds read in the Linux kernel's usbio module (usb: misc: usbio). The function usbio_bulk_msg() copies a device-supplied length (bpkt_len) from the bulk IN buffer, but only validates it against txbuf_len instead of rxbuf_len. A malicious or malfunctioning USB device t...
