Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Memory leak (CVE-ID: CVE-2022-1012)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient randomization in the net/ipv4/tcp.c when calculating port offsets in Linux kernel cause by small table perturb size. A remote attacker can cause memory leak and gain access to sensitive information.
2) Use of insufficiently random values (CVE-ID: CVE-2022-32296)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to Linux kernel allowing TCP servers to identify clients by observing what source ports are used. A local user can gain unauthorized access to sensitive information on the system.
3) Information disclosure (CVE-ID: CVE-2022-21123)
The 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.
4) Information disclosure (CVE-ID: CVE-2022-21125)
The 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.
5) Information disclosure (CVE-ID: CVE-2022-21166)
The 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.
