CVE-2026-46579 1 Redhat 2 Openshift Container Platform, Openshift Router 2026-07-30 N/A 7.4 HIGH
A flaw was found in the OpenShift Router. When a Route has `insecureEdgeTerminationPolicy` set to Allow, the HTTP frontend does not remove `X-SSL-Client-*` headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted `X-SSL-Client-*` headers. As a result, backends relying on these headers for mutual TLS (Transport Layer Security) authentication can be bypassed, enabling the attacker to impersonate client certificate identities.
CVE-2026-55653 2 Openbsd, Redhat 4 Openssh, Enterprise Linux, Hardened Images and 1 more 2026-07-30 N/A 4.3 MEDIUM
A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS).
CVE-2026-54100 1 Redhat 2 Openshift Container Platform, Windows Machine Config Operator 2026-07-29 N/A 8.3 HIGH
A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. WMCO establishes SSH connections to Windows worker nodes without verifying the remote server host key. An adjacent-network attacker who can intercept or redirect WMCO's SSH session can capture WICD and kubelet bootstrap credentials transferred during node configuration, enabling compromise of Windows node identities in the cluster.
CVE-2026-54099 1 Redhat 2 Openshift Container Platform, Windows Machine Config Operator 2026-07-29 N/A 8.8 HIGH
A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. The WICD CSR auto-approver validates that a Certificate Signing Request contains the organization system:wicd-nodes but does not reject additional organization values such as system:masters. A compromised Windows worker node that holds WICD credentials can submit a CSR that is auto-approved and signed by the cluster, yielding a client certificate that grants cluster-administrator privileges and enabling full cluster takeover.
CVE-2025-5318 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Openshift Container Platform 2026-07-28 N/A 8.1 HIGH
A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.
CVE-2026-31431 10 Amazon, Arista, Canonical and 7 more 47 Amazon Linux, Cloudvision Agni, Cloudvision Portal and 44 more 2026-07-28 N/A 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-2026-4878 2 Libcap Project, Redhat 3 Libcap, Enterprise Linux, Openshift Container Platform 2026-07-28 N/A 6.7 MEDIUM
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.
CVE-2026-48864 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-07-27 N/A 7.8 HIGH
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
CVE-2025-6170 2 Redhat, Xmlsoft 4 Enterprise Linux, Jboss Core Services, Openshift Container Platform and 1 more 2026-07-27 N/A 2.5 LOW
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
CVE-2026-1784 1 Redhat 1 Openshift Container Platform 2026-07-27 N/A 8.8 HIGH
The Route OpenShift resource allows to define routes to make pods reachable at a subdomain through HAProxy. It was found that the checks performed on the spec.path YAML stanza in a Route document was insufficient and could allow a controlled injection of the HAProxy configuration.
CVE-2025-5914 2 Libarchive, Redhat 3 Libarchive, Enterprise Linux, Openshift Container Platform 2026-07-27 N/A 7.8 HIGH
A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a denial-of-service condition.
CVE-2024-12085 8 Almalinux, Archlinux, Gentoo and 5 more 22 Almalinux, Arch Linux, Linux and 19 more 2026-07-26 N/A 7.5 HIGH
A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.
CVE-2026-4480 2 Redhat, Samba 3 Enterprise Linux, Openshift Container Platform, Samba 2026-07-24 N/A 9.0 CRITICAL
A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the "print command" setting via the "%J" substitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system.
CVE-2026-9150 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-07-23 N/A 6.5 MEDIUM
A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.
CVE-2026-42010 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-07-23 N/A 7.1 HIGH
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
CVE-2026-42009 2 Gnu, Redhat 14 Gnutls, Enterprise Linux, Enterprise Linux For Els and 11 more 2026-07-23 N/A 7.5 HIGH
A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service.
CVE-2026-9149 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-07-23 N/A 6.5 MEDIUM
A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).
CVE-2026-3833 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-07-22 N/A 6.5 MEDIUM
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-10533 1 Redhat 1 Openshift Container Platform 2026-07-22 N/A 5.0 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-2026-42965 1 Redhat 2 Openshift Container Platform, Openshift Router 2026-07-21 N/A 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.
