| CVE-2026-58216 | 2 Redhat, Samba | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-07-31 | 5.3 Medium |
| An out-of-bounds read flaw was found in Samba's Kerberos Key Distribution Center's (KDC) password change (kpasswd) service. When processing malformed ASN.1-encoded Kerberos password change request, Samba server miscalculates the structure size and attempts to read up to six bytes beyond the end of the allocated buffer. While this out-of-bounds read typically results in a harmless decryption failure, if the read hits unmapped memory, it causes the KDC process to crash. An authenticated attacker can send a specially crafted kpasswd request containing malformed ASN.1 data to trigger the out-of-bounds read, which may cause the KDC process to terminate, resulting in a denial of service. | ||||
| CVE-2026-9150 | 3 Opensuse, Red Hat, Redhat | 11 Libsolv, Red Hat Satellite 6, Enterprise Linux and 8 more | 2026-07-31 | 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-2026-9149 | 3 Opensuse, Red Hat, Redhat | 12 Libsolv, Red Hat Satellite 6, Enterprise Linux and 9 more | 2026-07-31 | 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-2026-16530 | 1 Redhat | 3 Enterprise Linux, Openshift, Openshift Container Platform | 2026-07-30 | 6.5 Medium |
| A flaw was found in the PCP (Performance Co-Pilot) `pmproxy` service. A remote attacker can exploit a vulnerability in the `pmLogLoadInDom()` function by sending a specially crafted request. This bypasses a critical bounds check, which can lead to the `pmproxy` service crashing, causing a Denial of Service (DoS). Additionally, this flaw may enable the leakage of sensitive information from the system's memory. | ||||
| CVE-2026-58218 | 2 Redhat, Samba | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-07-30 | 5.3 Medium |
| A flaw was found in Samba's internal DNS server where unauthenticated TKEY registration requests were added to the TKEY name cache before being rejected. A remote, unauthenticated attacker can exploit this behavior by sending a large number of TKEY requests with arbitrary names, exhausting the cache and evicting legitimate TKEY entries. This can prevent legitimate TSIG authentication for signed DNS queries, resulting in a denial of service. | ||||
| CVE-2026-58222 | 2 Redhat, Samba | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-07-30 | 8.8 High |
| A security flaw combining LDAP filter injection and improper authorization checks was found in Samba Active Directory Domain Controller (AD DC). When processing LDAP Compare requests, Samba fails to properly validate user-supplied attribute names and executes the resulting internal database search in a trusted context, bypassing normal Access Control List (ACL) enforcement. An authenticated low-privilege domain user can exploit these flaws to disclose confidential Active Directory attributes that would normally be inaccessible. The disclosed information may be leveraged to derive sensitive authentication material, potentially leading to privilege escalation and complete domain compromise. For example: In deployments configured with Group Managed Service Accounts (gMSAs), an attacker can extract the "msKds-RootKeyData" attribute and derive gMSA passwords offline, potentially leading to complete domain compromise if privileged gMSAs are present. | ||||
| CVE-2026-18220 | 2 Gnu, Redhat | 6 Binutils, Enterprise Linux, Hardened Images and 3 more | 2026-07-30 | 7.8 High |
| An out-of-bounds write vulnerability was found in the BFD library's DLX ELF backend (bfd/elf32-dlx.c) in GNU binutils. The dlx_rtype_to_howto() function maps ELF relocation types to internal howto structures but fails to perform adequate bounds checking on attacker-controlled relocation type values (via ELF32_R_TYPE(r_info)) before indexing into the dlx_elf_howto_table[] array. The DLX relocation type number space is non-contiguous (basic types 0-6, extended types at 0x10000+), but the default case in the switch statement allows arbitrary index values to reach the array access. A specially crafted ELF/DLX object file can trigger this out-of-bounds write when processed by any BFD-consuming tool (objdump, readelf, strip, ld, nm, objcopy). The vulnerability has been demonstrated to achieve arbitrary code execution via a File Stream Oriented Programming (FSOP) attack against glibc FILE structures (stderr), redirecting control flow to system(). Attack scenarios include CI/CD pipelines performing automated binary analysis, developer workstations running objdump/readelf on untrusted binaries, automated security scanning or malware analysis tools invoking binutils, and package build systems processing third-party code. Note: This vulnerability is only exploitable when binutils is built with the DLX backend enabled (typically via --enable-targets=all). | ||||
| CVE-2026-16531 | 1 Redhat | 3 Enterprise Linux, Openshift, Openshift Container Platform | 2026-07-30 | 5.3 Medium |
| An unauthenticated remote attacker can exploit a path traversal vulnerability in the PCP pmproxy logger servlet using a crafted hostname. This allows arbitrary file and directory creation, potentially leading to a denial of service. | ||||
| CVE-2026-4948 | 2 Firewalld, Redhat | 5 Firewalld, Enterprise Linux, Firewalld and 2 more | 2026-07-30 | 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-2026-15003 | 2 Gnu, Redhat | 6 Binutils, Enterprise Linux, Hardened Images and 3 more | 2026-07-28 | 5.6 Medium |
| A flaw was found in the GNU Binutils (Binary Utilities) linker. This vulnerability, a heap-buffer-overflow read (CWE-125), occurs when the linker processes a specially crafted 32-bit XCOFF (Extended Common Object File Format) object file. An attacker could exploit this by providing a malicious file, leading to an out-of-bounds read of memory. This can result in information disclosure, potentially revealing sensitive heap data, and a Denial of Service (DoS) due to the linker crashing. | ||||
| CVE-2026-12505 | 1 Redhat | 4 Cifs-utils, Enterprise Linux, Openshift and 1 more | 2026-07-28 | 7.8 High |
| A flaw was found in the cifs-utils package where the cifs.upcall helper fails to securely drop its root privileges before looking up user information inside a user-controlled environment. A local, low privileged attacker can exploit this by using a crafted request_key payload to trick the root-owned helper into entering a custom environment (namespace) containing a malicious NSS module. This forces the system to load the attacker's controlled NSS Module and configuration, allowing them to execute arbitrary commands as the root user, elevating their privileges and fully compromising the system. | ||||
| CVE-2026-54099 | 1 Redhat | 5 Openshift, Openshift Container Platform, Openshift For Windows Containers and 2 more | 2026-07-28 | 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-2026-54100 | 1 Redhat | 5 Openshift, Openshift Container Platform, Openshift For Windows Containers and 2 more | 2026-07-28 | 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-2026-16517 | 2 Libarchive, Redhat | 6 Libarchive, Enterprise Linux, Hardened Images and 3 more | 2026-07-27 | 2.9 Low |
| A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption. | ||||
| CVE-2026-16552 | 2 Redhat, Systemd | 4 Enterprise Linux, Hardened Images, Openshift Container Platform and 1 more | 2026-07-27 | 6.3 Medium |
| The reported issue is invalid, as it requires root privileges to reproduce, and it is out of scope of the threat model of the affected component. | ||||
| CVE-2026-17527 | 1 Redhat | 2 Container Native Virtualization, Openshift Virtualization | 2026-07-27 | 7.7 High |
| In containerized-data-importer (CDI), the aggregated cdi.kubevirt.io:view ClusterRole, intended to provide read-only access to CDI resources, includes a rule granting create on the datavolumes/source subresource. CDI's DataVolume clone authorization accepts this permission as sufficient to authorize cloning the contents of any PVC the caller can name, without requiring write access to the source namespace. A user or service account bound to the view role, commonly granted cluster-wide via ClusterRoleBinding, who also has ordinary write access (edit/admin) to any single namespace, can use this to exfiltrate the contents of any PVC in the cluster into a namespace they control, bypassing namespace isolation and the read-only guarantee of the view role. | ||||
| CVE-2026-15811 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-07-23 | 5.8 Medium |
| A vulnerability was found in kronosnet's (version <=1.34) cryptographic configuration management. The framework does not correctly zero-out or wipe sensitive memory segments after executing changes to its cryptographic configuration. This omission leaves raw encryption keys resident in memory after the associated structures are freed. A local attacker capable of leveraging memory disclosure techniques could exploit this flaw to retrieve the active encryption key, allowing them to decrypt cluster network communications or inject malicious packets to cause severe high-availability cluster instability. | ||||
| CVE-2025-10911 | 1 Redhat | 11 Discovery, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-07-23 | 5.5 Medium |
| A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash. | ||||
| CVE-2026-10649 | 2 Clusterlabs, Redhat | 10 Pacemaker, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-07-22 | 8.6 High |
| A flaw was found in Pacemaker. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the remote message decompression process. By sending a specially crafted compressed remote message before authentication, an attacker can cause memory corruption, leading to a denial of service (DoS) in the CIB remote listener. This can result in the affected service crashing. | ||||
| CVE-2026-16445 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Openshift | 2026-07-22 | 7.5 High |
| A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP options, such as a malicious root-path, next-server, or bootfile name, to a system using dracut's NetworkManager-based initrd network module. These options are improperly handled and written into a temporary shell script without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs during system boot. | ||||
