  2. Vulnerabilities (CVE)
  3. CVE-2024-43883
In the Linux kernel, the following vulnerability has been resolved: usb: vhci-hcd: Do not drop references before new references are gained At a few places the driver carries stale pointers to references that can still be used. Make sure that does not happen. This strictly speaking closes ZDI-CAN-22273, though there may be similar races in the driver.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: vhci-hcd: no descartar referencias antes de obtener nuevas referencias. En algunos lugares, el controlador incluye punteros obsoletos a referencias que aún se pueden utilizar. Asegúrate de que eso no suceda. Esto cierra estrictamente ZDI-CAN-22273, aunque puede haber ejecuciones similares en el driver.
