Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ovl: relax WARN_ON in ovl_verify_area()

syzbot hit an assertion in copy up data loop which looks like it is
the result of a lower file whose size is being changed underneath
overlayfs.

This type of use case is documented to cause undefined behavior, so
returning EIO error for the copy up makes sense, but it should not be
causing a WARN_ON assertion.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ovl: relax WARN_ON en ovl_verify_area() syzbot alcanzó una afirmación en el bucle de copia de datos que parece ser el resultado de un archivo inferior cuyo tamaño se está cambiando debajo de overlayfs. Está documentado que este tipo de caso de uso causa un comportamiento indefinido, por lo que devolver un error EIO para la copia tiene sentido, pero no debería causar una afirmación WARN_ON.
