CVE-2021-4028

kernel: use-after-free in RDMA listen()

A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system.

CVE-2021-4024

podman: podman machine spawns gvproxy with port bound to all IPs

A flaw was found in podman. The `podman machine` function (used to create and manage Podman virtual machine containing a Podman process) spawns a `gvproxy` process on the host system. The `gvproxy` API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall, an attacker can potentially use the `gvproxy` API to forward ports on the host to ports in the VM, making private services on the VM accessible to the network. This issue could be also used to interrupt the host's services by forwarding all ports to the VM.

CVE-2021-4023

kernel: Improper IO-uring request cancellation operation allows local users to cause a crash

A flaw was found in the io-workqueue implementation in the Linux kernel versions prior to 5.15-rc1. The kernel can panic when an improper cancellation operation triggers the submission of new io-uring operations during a shortage of free space. This flaw allows a local user with permissions to execute io-uring requests to possibly crash the system.

CVE-2021-4007

Rapid7 Insight Agent Privilege Escalation

Rapid7 Insight Agent, versions 3.0.1 to 3.1.2.34, suffer from a local privilege escalation due to an uncontrolled DLL search path. Specifically, when Insight Agent versions 3.0.1 to 3.1.2.34 start, the Python interpreter attempts to load python3.dll at "C:\DLLs\python3.dll," which normally is writable by locally authenticated users. Because of this, a malicious local user could use Insight Agent's startup conditions to elevate to SYSTEM privileges. This issue was fixed in Rapid7 Insight Agent 3.1.2.35. This vulnerability is a regression of CVE-2019-5629.
