Descriptions
Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740). Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend (CVE-2022-33741, CVE-2022-33742).
Unas fuga de datos de frontends de disco/NIC de Linux Este registro de información de CNA se relaciona con múltiples CVE; el texto explica qué aspectos/vulnerabilidades corresponden a qué CVE.] Las interfaces de dispositivos Linux Block y Network PV no ponen a cero las regiones de memoria antes de compartirlas con el backend (CVE-2022-26365, CVE-2022-33740). Además, la granularidad de la tabla de concesión no permite compartir menos de una página de 4K, lo que hace que los datos no relacionados que residen en la misma página de 4K que los datos compartidos con un backend sean accesibles por dicho backend (CVE-2022-33741, CVE-2022- 33742)
