Descriptions
The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory objects were handled when they were being used to store a surface. When running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially use this flaw to escalate their privileges.
Los cambios en el recuento de referencias realizados como parte de las correcciones CVE-2023-33951 y CVE-2023-33952 expusieron una falla de use-after-free en la forma en que se manejaban los objetos de memoria cuando se usaban para almacenar una superficie. Cuando se ejecuta dentro de un invitado de VMware con la aceleración 3D habilitada, un usuario local sin privilegios podrÃa utilizar esta falla para aumentar sus privilegios.
Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service. It was discovered that the Habana's AI Processors driver in the Linux kernel did not properly initialize certain data structures before passing them to user space. A local attacker could use this to expose sensitive information.
