| CVE-2026-3238 | 2 Redhat, Samba | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-06-09 | 7.5 High |
| A flaw was found in Samba’s WINS server component when running as an Active Directory Domain Controller. The WINS protocol handlers for certain request types did not properly validate incoming packets, allowing an unauthenticated remote attacker to trigger a NULL pointer dereference and crash the WINS service using specially crafted UDP packets. | ||||
| CVE-2026-42965 | 1 Redhat | 3 Openshift, Openshift Container Platform, Openshift Router | 2026-06-08 | 7.7 High |
| A flaw was found in the OpenShift Router. A user with EndpointSlice write access can exploit this vulnerability by creating a Service backed by an FQDN (Fully Qualified Domain Name) EndpointSlice that resolves to a cloud metadata endpoint. This allows the router to proxy requests to the cloud metadata endpoint, leading to the disclosure of instance credentials and other sensitive metadata. This bypasses previous security measures for validating IP addresses. | ||||
| CVE-2026-10533 | 1 Redhat | 2 Openshift, Openshift Container Platform | 2026-06-08 | 5 Medium |
| A flaw was found in OpenShift Container Platform. Completed pods with restartPolicy: Never do not count toward ResourceQuota pod limits, and Kubernetes events are not quota-scoped. A non-privileged user who can create pods in a namespace can exploit this to generate a large volume of events that accumulate in etcd, causing API server performance degradation across the cluster. | ||||
| CVE-2026-10805 | 1 Redhat | 8 Enterprise Linux, Jboss Enterprise Application Platform Expansion Pack, Jbosseapxp and 5 more | 2026-06-05 | 6.7 Medium |
| A flaw was found in NetworkManager. This local privilege escalation vulnerability exists in NetworkManager's dhclient backend when processing malformed Manufacturer Usage Description (MUD) URLs. A local user can exploit this flaw to escalate privileges by triggering a script via a crafted MUD URL, provided an administrator has explicitly configured NetworkManager to use dhclient. This issue does not affect default configurations of NetworkManager. | ||||
| CVE-2026-10843 | 1 Redhat | 2 Openshift, Openshift Container Platform | 2026-06-05 | 7.2 High |
| A flaw was found in the OpenShift Cloud Credential Operator Mint-mode IAM policies for AWS. Operator credentials are provisioned with account-wide scope for destructive actions rather than being restricted to cluster-owned resources, enabling cross-scope impact after credential compromise. | ||||
| CVE-2026-5367 | 1 Redhat | 4 Enterprise Linux, Fast Datapath, Openshift and 1 more | 2026-06-01 | 8.6 High |
| A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the disclosure of sensitive information stored in heap memory, which is then returned to the attacker's virtual machine port. | ||||
| CVE-2021-4104 | 4 Apache, Fedoraproject, Oracle and 1 more | 59 Log4j, Fedora, Advanced Supply Chain Planning and 56 more | 2026-05-28 | 7.5 High |
| JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | ||||
| CVE-2026-35091 | 2 Corosync, Redhat | 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-05-26 | 8.2 High |
| A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory contents | ||||
| CVE-2026-35092 | 2 Corosync, Redhat | 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-05-26 | 7.5 High |
| A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol (UDP) packets. This can cause the service to crash, leading to a denial of service. This vulnerability specifically affects Corosync deployments configured to use totemudp/totemudpu mode. | ||||
| CVE-2026-31431 | 11 Amazon, Arista, Canonical and 8 more | 43 Amazon Linux, Cloudvision Agni, Cloudvision Portal and 40 more | 2026-05-21 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated data. There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly. | ||||
| CVE-2026-6843 | 2 Gnu, Redhat | 5 Nano, Enterprise Linux, Nano and 2 more | 2026-05-20 | 5.5 Medium |
| A flaw was found in nano. A local user could exploit a format string vulnerability in the `statusline()` function. By creating a directory with a name containing `printf` specifiers, the application attempts to display this name, leading to a segmentation fault (SEGV). This results in a Denial of Service (DoS) for the `nano` application. | ||||
| CVE-2026-6844 | 2 Gnu, Redhat | 6 Binutils, Enterprise Linux, Hardened Images and 3 more | 2026-05-20 | 5.5 Medium |
| A flaw was found in the `readelf` utility of the binutils package. A local attacker could exploit two Denial of Service (DoS) vulnerabilities by providing a specially crafted Executable and Linkable Format (ELF) file. One vulnerability, a resource exhaustion (CWE-400), can lead to an out-of-memory condition. The other, a null pointer dereference (CWE-476), can cause a segmentation fault. Both issues can result in the `readelf` utility becoming unresponsive or crashing, leading to a denial of service. | ||||
| CVE-2026-0966 | 2 Libssh, Redhat | 6 Libssh, Enterprise Linux, Hardened Images and 3 more | 2026-05-19 | 8.2 High |
| A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to `SSH_LOG_PACKET (3)` or higher. Successful exploitation could lead to a self-Denial of Service of the per-connection daemon process. | ||||
| CVE-2026-0964 | 2 Libssh, Redhat | 6 Libssh, Enterprise Linux, Hardened Images and 3 more | 2026-05-19 | 6.3 Medium |
| A malicious SCP server can send unexpected paths that could make the client application override local files outside of working directory. This could be misused to create malicious executable or configuration files and make the user execute them under specific consequences. This is the same issue as in OpenSSH, tracked as CVE-2019-6111. | ||||
| CVE-2026-4948 | 2 Firewalld, Redhat | 5 Firewalld, Enterprise Linux, Firewalld and 2 more | 2026-05-15 | 5.5 Medium |
| A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations. | ||||
| CVE-2026-6732 | 2 Redhat, Xmlsoft | 8 Enterprise Linux, Hardened Images, Hummingbird and 5 more | 2026-05-15 | 6.5 Medium |
| A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable. | ||||
| CVE-2026-6862 | 2 Redhat, Ubuntu | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-05-13 | 5.5 Medium |
| A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI (Extensible Firmware Interface) device path node header. A local user could exploit this vulnerability by providing a specially crafted device path node. This can lead to infinite recursion, causing stack exhaustion and a process crash, resulting in a denial of service (DoS). | ||||
| CVE-2023-44487 | 33 Akka, Amazon, Apache and 30 more | 378 Http Server, Opensearch Data Prepper, Apisix and 375 more | 2026-05-12 | 7.5 High |
| The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | ||||
| CVE-2025-26465 | 4 Debian, Netapp, Openbsd and 1 more | 9 Debian Linux, Active Iq Unified Manager, Ontap and 6 more | 2026-05-12 | 6.8 Medium |
| A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. | ||||
| CVE-2024-6387 | 13 Almalinux, Amazon, Apple and 10 more | 85 Almalinux, Amazon Linux, Macos and 82 more | 2026-05-12 | 8.1 High |
| A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. | ||||
