| CVE-2021-3656 | 3 Fedoraproject, Linux, Redhat | 26 Fedora, Linux Kernel, 3scale Api Management and 23 more | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. | |||||

| CVE-2021-3636 | 1 Redhat | 1 Openshift | 2024-11-21 | 4.1 MEDIUM | 4.6 MEDIUM |
| 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. | |||||
| CVE-2021-3635 | 3 Fedoraproject, Linux, Redhat | 3 Fedora, Linux Kernel, Enterprise Linux | 2024-11-21 | 4.9 MEDIUM | 4.4 MEDIUM |
| A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands. | |||||
| CVE-2021-3634 | 6 Debian, Fedoraproject, Libssh and 3 more | 7 Debian Linux, Fedora, Libssh and 4 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| A flaw has been found in libssh in versions prior to 0.9.6. The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called secret_hash and the other session_id. Initially, both of them are the same, but after key re-exchange, previous session_id is kept and used as an input to new secret_hash. Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. But the key re-exchange operation can also change the key exchange method, which can be based on hash of different size, eventually creating "secret_hash" of different size than the session_id has. This becomes an issue when the session_id memory is zeroed or when it is used again during second key re-exchange. | |||||
| CVE-2021-3632 | 1 Redhat | 3 Enterprise Linux, Keycloak, Single Sign-on | 2024-11-21 | N/A | 7.5 HIGH |
