CVE-2021-3636 – openshift: Injected service-ca.crt incorrectly contains additional internal CAs
https://notcve.org/view.php?id=CVE-2021-3636
It was found in OpenShift, before version 4.8, that the generated certificate for the in-cluster Service CA, incorrectly included additional certificates. The Service CA is automatically mounted into all pods, allowing them to safely connect to trusted in-cluster services that present certificates signed by the trusted Service CA. The incorrect inclusion of additional CAs in this certificate would allow an attacker that compromises any of the additional CAs to masquerade as a trusted in-cluster service. Se encontró en OpenShift, anterior a versión 4.8, que el certificado generado para la CA de servicio en el clúster, incluía incorrectamente certificados adicionales. La CA de servicio se monta automáticamente en todos los pods, permitiéndoles conectarse de forma segura a los servicios confiables del clúster que presentan certificados firmados por la CA de servicio confiable. • https://bugzilla.redhat.com/show_bug.cgi?id=1978621 https://access.redhat.com/security/cve/CVE-2021-3636 • CWE-287: Improper Authentication CWE-295: Improper Certificate Validation •
CVE-2021-3609 – kernel: race condition in net/can/bcm.c leads to local privilege escalation
https://notcve.org/view.php?id=CVE-2021-3609
.A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.

CVE-2021-3560 – Red Hat Polkit Incorrect Authorization Vulnerability
https://notcve.org/view.php?id=CVE-2021-3560
It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se ha detectado que polkit podía ser engañado para omitir las comprobaciones de credenciales para las peticiones de D-Bus, elevando los privilegios del solicitante al usuario root.
