Descriptions

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

block: Fix iterating over an empty bio with bio_for_each_folio_all

If the bio contains no data, bio_first_folio() calls page_folio() on a
NULL pointer and oopses. Move the test that we've reached the end of
the bio from bio_next_folio() to bio_first_folio().

[axboe: add unlikely() to error case]

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bloque: corrige la iteración sobre una biografía vacía con bio_for_each_folio_all Si la biografía no contiene datos, bio_first_folio() llama a page_folio() en un puntero NULL y ¡vaya! Mueve la prueba de que hemos llegado al final de la biografía de bio_next_folio() a bio_first_folio(). [axboe: agregue improbable() al caso de error]
