  3. CVE-2023-52806
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fix possible null-ptr-deref when assigning a stream While AudioDSP drivers assign streams exclusively of HOST or LINK type, nothing blocks a user to attempt to assign a COUPLED stream. As supplied substream instance may be a stub, what is the case when code-loading, such scenario ends with null-ptr-deref.

Summary
  • (es) En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: ALSA: hda: Corrige posible null-ptr-deref al asignar un flujo. Si bien los controladores AudioDSP asignan flujos exclusivamente de tipo HOST o LINK, nada impide que un usuario intente asignar un flujo ACOPLADO. Como la instancia de subsecuencia proporcionada puede ser un código auxiliar, cuál es el caso cuando se carga el código, dicho escenario termina con null-ptr-deref.
