CVE-ID: CVE-2022-21123
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows an attacker to gain access to potentially sensitive information.
The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.

CVSSv3.1:
CVE-ID: CVE-2018-13405
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to create arbitrary files on the target system.
The vulnerability exists due to the inode_init_owner function, as defined in the fs/inode.c source code file, allows the creation of arbitrary files in set-group identification (SGID) directories. A local attacker can create arbitrary files with unintended group ownership.
