    Medium [CVE-2026-74681] check ibuf_len against rxbuf_len in bulk msg

    CVE-2026-74681Source published Source updated

    In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: check ibuf_len against rxbuf_len in bulk msg ibuf_len is the bulk IN (receive) buffer size, but the EMSGSIZE check in usbio_bulk_msg() compares it against txbuf_len — the bulk OUT endpoint size. Both are taken independently from different endpoints in usbio_probe(), so the check is wrong when they differ. Use rxbuf_len for the IN direction. This matches the buffer that actually holds the response data. A flaw was found in the Linux kernel's USB subsystem, specifically within the `usbio` module. An incorrect buffer size validation occurs in the `usbio_bulk_msg()` function, where the bulk IN (receive) buffer size is mistakenly compared against the bulk OUT endpoint size instead of the actual receive…
