  3. CVE-2023-52926
In the Linux kernel, the following vulnerability has been resolved: IORING_OP_READ did not correctly consume the provided buffer list when read i/o returned < 0 (except for -EAGAIN and -EIOCBQUEUED return). This can lead to a potential use-after-free when the completion via io_rw_done runs at separate context.

Summary
  • (es) Se ha resuelto una vulnerabilidad en el kernel de Linux consistente en que la operación IORING_OP_READ no consumia correctamente la lista de buffers proporcionada cuando la lectura de entrada salida devolvía un valor &lt; 0 (excepto los casos en que devolvía -EAGAIN y -EIOCBQUEUED). Esto puede llevar a un potencial uso después de liberar memoria cuando el completado via io_rw_done se ejecuta en un contexto separado.
