CVE-2022-0851 – convert2rhel: Activation key passed via command line by code
https://notcve.org/view.php?id=CVE-2022-0851
There is a flaw in convert2rhel. When the --activationkey option is used with convert2rhel, the activation key is subsequently passed to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the activation key via the process command line via e.g. htop or ps. The specific impact varies upon the subscription, but generally this would allow an attacker to register systems purchased by the victim until discovered; a form of fraud. This could occur regardless of how the activation key is supplied to convert2rhel because it involves how convert2rhel provides it to subscription-manager.

CVE-2021-3864
https://notcve.org/view.php?id=CVE-2021-3864
A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants. The prerequisite is a SUID binary that sets real UID equal to effective UID, and real GID equal to effective GID. The descendant will then have a dumpable value set to 1. As a result, if the descendant process crashes and core_pattern is set to a relative value, its core dump is stored in the current directory with uid:gid permissions. An unprivileged local user with eligible root SUID binary could use this flaw to place core dumps into root-owned directories, potentially resulting in escalation of privileges. • https://access.redhat.com/security/cve/CVE-2021-3864 https://bugzilla.redhat.com/show_bug.cgi?id=2015046 https://lore.kernel.org/all/20211221021744.864115-1-longman%40redhat.com https://lore.kernel.org/all/20211226150310.GA992%401wt.eu https://lore.kernel.org/lkml/20211228170910.623156-1-wander%40redhat.com https://security-tracker.debian.org/tracker/CVE-2021-3864 https://www.openwall.com/lists/oss-security/2021/10/20/2 • CWE-284: Improper Access Control •
CVE-2022-34303 – shim: 3rd party shim allow secure boot bypass
https://notcve.org/view.php?id=CVE-2022-34303
A flaw was found in Eurosoft bootloaders before 2022-06-01. An attacker may use this bootloader to bypass or tamper with Secure Boot protections. In order to load and execute arbitrary code in the pre-boot stage, an attacker simply needs to replace the existing signed bootloader currently in use with this bootloader. Access to the EFI System Partition is required for booting using external media.
