CVE-2024-26632

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]

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]

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service.
