CVE-2026-23347

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-23347
In the Linux kernel, the following vulnerability has been resolved: can: usb: f81604: correctly anchor the urb in the read bulk callback When submitting an urb, that is using the anchor pattern, it needs to be anchored before submitting it otherwise it could be leaked if usb_kill_anchored_urbs() is called. This logic is correctly done elsewhere in the driver, except in the read bulk callback so do that here also.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: can: usb: f81604: anclar correctamente el urb en la devolución de llamada de lectura masiva Al enviar un urb, que está usando el patrón de anclaje, necesita ser anclado antes de enviarlo, de lo contrario, podría filtrarse si se llama a usb_kill_anchored_urbs(). Esta lógica se realiza correctamente en otras partes del controlador, excepto en la devolución de llamada de lectura masiva, así que hazlo aquí también.
