CVE-2026-5135 2 Redhat, Theforeman 3 Enterprise Linux, Satellite, Foreman 2026-07-09 N/A 6.5 MEDIUM
A flaw was found in Foreman. This broken access control vulnerability allows an authenticated user with host-edit permissions to retarget an existing lookup value override to a different host. This is achieved by modifying the match field through nested host attributes, effectively bypassing authorisation checks. The consequence is the potential for unauthorised modification of managed host configurations across different organisational and location boundaries.
CVE-2026-5138 2 Redhat, Theforeman 3 Enterprise Linux, Satellite, Foreman 2026-07-09 N/A 4.3 MEDIUM
A flaw was found in Foreman. An authenticated user with host-edit permissions could exploit a cross-tenant information disclosure vulnerability. This flaw occurs because the taxonomy_scope controller method does not properly validate organization and location IDs from nested request parameters, bypassing existing authorization checks. This allows the user to leak sensitive infrastructure metadata, including subnet topology, IP ranges, gateways, DNS servers, and VLAN IDs, from organizations and locations they are not authorized to access.
CVE-2026-5142 2 Redhat, Theforeman 3 Enterprise Linux, Satellite, Foreman 2026-07-09 N/A 6.5 MEDIUM
A flaw was found in foreman. Authenticated users with 'view_keypairs' permission can bypass taxonomy scoping, allowing them to download private SSH (Secure Shell) keys from other organizations by directly querying key pair IDs. This vulnerability leads to cross-tenant data exposure in multi-tenant deployments, potentially compromising sensitive information.
CVE-2026-11819 1 Redhat 1 Enterprise Linux 2026-07-08 N/A 5.5 MEDIUM
Module: plugins/modules/keyring_info.py CVSS 3.1: 5.5 MEDIUM — AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N Issue: The module retrieves a passphrase from the OS native keyring (GNOME Keyring, macOS Keychain, Windows Credential Manager) and places it directly into result["passphrase"] with no output suppression, no no_log protection, and no documentation warning. Root Cause: Line 105 (protected): keyring_password=dict(type="str", required=True, no_log=True) Line 127 (NOT protected): result["passphrase"] = passphrase Observed Output: { "changed": false, "passphrase": "MyMasterP@ssw0rd!SSH_Key_Secret" } Visible via register + debug: { "keyring_result": { "changed": false, "passphrase": "MyMasterP@ssw0rd!SSH_Key_Secret" } } Impact: Master passwords, SSH key passphrases and service credentials appear in all Ansible output register: keyring_result followed by debug: var=keyring_result prints passphrase in full Ansible fact caching backends (Redis, JSON file, memcached) may persist the passphrase AWX/Tower job logs silently store the live credential Fix: module.exit_json(changed=False, passphrase=passphrase, _ansible_no_log=True) Also add a documentation warning requiring callers to use no_log: true at the task level.

CVE-2026-12549 2 Gnome, Redhat 2 Libsoup, Enterprise Linux 2026-07-08 N/A 4.8 MEDIUM
The fix for CVE-2026-2443 was regressed by a subsequent rework commit that replaced specific overflow checks with a general signed comparison. When a client sends a Range request with a suffix length exceeding the content size, the resulting negative start value is not properly clamped, leading to malformed HTTP 206 responses and log flooding.
CVE-2026-12725 2 Redhat, Thekelleys 3 Enterprise Linux, Openshift Container Platform, Dnsmasq 2026-07-08 N/A 5.9 MEDIUM
A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both enabled, logging of DS or DNSKEY replies containing unsupported algorithm or digest types can cause dnsmasq to write past the end of an internal logging buffer. A remote attacker able to supply such a DNS response may crash the dnsmasq process, resulting in denial of service.
CVE-2026-10609 1 Redhat 2 Cluster Logging Operator, Logging Subsystem For Red Hat Openshift 2026-07-08 N/A 6.8 MEDIUM
A missing authorization flaw was found in the OpenShift Cluster Logging Operator. The operator creates and forwards ServiceAccount tokens to output destinations without verifying that the ClusterLogForwarder creator has permission to use those credentials, allowing a delegated editor to exfiltrate SA tokens and escalate privileges.
CVE-2026-12969 2 Redhat, Thekelleys 2 Enterprise Linux, Dnsmasq 2026-07-08 N/A 5.3 MEDIUM
An out-of-bounds read vulnerability exists in dnsmasq's find_soa() function in src/rfc1035.c. When parsing NS section records, extract_name() is called with extrabytes=0, failing to validate that 10 additional bytes exist for fixed-length DNS record fields. A remote attacker controlling a DNS zone can exploit this via a crafted NXDOMAIN response to cause a 10-byte heap out-of-bounds read, potentially accessing stale data from prior transactions.
CVE-2026-13083 1 Redhat 1 Pen Drive 2026-07-08 N/A 6.9 MEDIUM
A flaw was found in the Pen Drive report generator. Cluster-sourced data is rendered into HTML reports without proper escaping or sanitization. An attacker with cluster administrator privileges can inject a stored cross-site scripting (XSS) payload into cluster objects (such as ClusterVersion spec.channel) that executes in the browser of any user who opens the generated HTML report.
CVE-2026-13595 2 Kernel, Redhat 4 Util-linux, Enterprise Linux, Hardened Images and 1 more 2026-07-08 N/A 6.8 MEDIUM
A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug events. This could lead to limited information disclosure or denial of service.
CVE-2026-57965 2 Redhat, Spice-space 2 Enterprise Linux, Spice-vdagent 2026-07-08 N/A 5.1 MEDIUM
A flaw was found in spice-vdagent. A malicious or compromised SPICE host can trigger an integer overflow by sending a specially crafted message. This vulnerability can lead to a heap buffer overflow, causing the spice-vdagent daemon to crash and resulting in a Denial of Service (DoS) for the virtual machine. This issue requires the SPICE host to be untrusted or compromised for exploitation.
CVE-2026-57966 2 Redhat, Spice-space 2 Enterprise Linux, Spice-vdagent 2026-07-08 N/A 4.4 MEDIUM
A path traversal vulnerability was found in spice-vdagent. This flaw allows a malicious or compromised SPICE host to write arbitrary files to any location on the guest operating system. This occurs because the filename provided by the SPICE host during file transfers is not properly sanitized before being used. An attacker could exploit this to write to sensitive locations with the privileges of the spice-vdagent process, typically the logged-in user. This issue requires the SPICE host to be untrusted or compromised for exploitation.
CVE-2018-10902 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2026-07-07 4.6 MEDIUM 7.8 HIGH
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.
CVE-2026-12993 1 Redhat 1 Build Of Apicurio Registry 2026-07-06 N/A 6.5 MEDIUM
A flaw was found in Apicurio Registry. The DocumentBuilderAccessor correctly blocks external DTD and schema access but does not disable DOCTYPE declarations or enable FEATURE_SECURE_PROCESSING. An attacker with artifact-write permission can upload XML documents with internal entity-expansion payloads (billion-laughs variant) that cause CPU and heap exhaustion, partially mitigated by the JAXP default 64,000 entity-expansion limit.
CVE-2026-12892 2 Gstreamer, Redhat 2 Gstreamer, Enterprise Linux 2026-07-06 N/A 4.4 MEDIUM
A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur during parsing. This happens when the parser attempts to check slice boundary information without first verifying that the NAL unit contains enough data beyond the extension header. An attacker could exploit this by tricking a user into opening a malicious H.264 video file, potentially causing the application to crash or leak a single byte of heap memory.
CVE-2026-13434 2 Kubevirt, Redhat 2 Kubevirt, Openshift Virtualization 2026-07-06 N/A 4.9 MEDIUM
A flaw was found in KubeVirt's network annotation generator. When a tenant creates a VirtualMachineInstance with a Multus network configuration, the supplied networkName value is written verbatim into the launcher pod's v1.multus-cni.io/default-network annotation without format validation or sanitization. The only admission check rejects empty strings; no DNS-1123 format validation, JSON detection, or special character rejection is performed. When the ExternalNetResourceInjection Beta feature gate is enabled (off by default, cluster-admin only), the NAD lookup that would otherwise catch malformed names is skipped by design. A tenant with kubevirt.io:edit permissions can inject a JSON-formatted NetworkSelectionElement array specifying an arbitrary namespace, NAD name, static IP address, and MAC address. Multus on the node parses this JSON and attaches the launcher pod to the specified network attachment in any namespace, enabling cross-namespace network access and IP/MAC impersonation on network segments normally segregated from tenant workloads. The ExternalNetResourceInjection feature gate was introduced in KubeVirt v1.8.0 (first shipped in OpenShift Virtualization 4.21).
CVE-2026-13201 2 Kubevirt, Redhat 2 Kubevirt, Openshift Virtualization 2026-07-06 N/A 7.3 HIGH
A flaw was found in KubeVirt's safepath package used by virt-handler. The OpenAtNoFollow function uses O_PATH|O_NOFOLLOW to obtain a file descriptor to a path leaf, but downstream operations resolve the path via /proc/self/fd/N using link-following syscalls. When the leaf is a symlink, the kernel dereferences it, defeating the intended no-follow protection. An attacker with access to a virt-launcher pod can exploit this to redirect virt-handler's IPC socket connections, including the notify socket used for VM domain lifecycle events. By hijacking this socket, the attacker can inject arbitrary domain events into virt-handler, causing it to take incorrect lifecycle actions, corrupt VM state in the Kubernetes API, or crash — resulting in sustained denial of VM management services for all virtual machines on the affected node. Additionally, the same symlink following flaw allows virt-handler to apply file ownership or permission changes to unintended host paths.
CVE-2026-13208 2 Kubevirt, Redhat 2 Kubevirt, Openshift Virtualization 2026-07-06 N/A 6.5 MEDIUM
A flaw was found in KubeVirt's virt-handler domain notify server. The gRPC handlers for HandleDomainEvent and HandleK8SEvent derive the VMI identity (namespace/name) solely from the request body without validating it against the connection's origin. Each virt-launcher pod connects through a per-VMI pipe socket, but no identity tag is propagated from the pipe path to the server handlers. This allows a compromised virt-launcher process to send forged domain lifecycle events for any other VMI scheduled on the same node, causing virt-handler to erroneously update that VMI's state and disrupt its lifecycle management.
CVE-2026-13218 2 Kubevirt, Redhat 2 Kubevirt, Openshift Virtualization 2026-07-06 N/A 4.2 MEDIUM
A flaw was found in KubeVirt's virt-handler network cache handling. The WriteToCachedFile function writes data to a launcher-rooted path using os.WriteFile and os.Chown without symlink protection. A user with access to the virt-launcher container can plant a symlink at the cache file path, causing virt-handler to follow it and overwrite an arbitrary host file with JSON content and change its ownership.
CVE-2026-13318 2 Kubevirt, Redhat 2 Kubevirt, Openshift Virtualization 2026-07-06 N/A 6.4 MEDIUM
A server-side request forgery (SSRF) flaw was found in KubeVirt's virt-api port-forward handler. When processing a port-forward request to a VirtualMachineInstance (VMI), virt-api reads the target IP from vmi.Status.Interfaces[0].IP and passes it directly to net.Dial() without validation. For VMIs using non-masquerade network bindings (bridge or secondary-only), this IP is reported by the QEMU guest agent running inside the VM and is fully controllable by the VM owner. An attacker with kubevirt.io:edit permissions can create a VM with a modified guest agent that reports an arbitrary IP address, then request port-forward to establish a bidirectional TCP tunnel from virt-api's cluster-internal network position to any routable destination, bypassing NetworkPolicy isolation.
