CWE-476 Sep 29, 2026
Kubevirt: kubevirt: virt-controller nil-pointer dereference via malformed ephemeral volume
A flaw was found in KubeVirt. An authenticated user with permission to create Virtual Machine Instances (VMIs) can cause a Denial of Service (DoS) by submitting a virtual machine definition with an empty ephemeral volume. The virt-controller component fails to properly validate the volume configuration, leading to an unhandled exception and application crash during processing. Because the malformed definition persists in the cluster, the controller enters a continuous crash loop, disrupting virtual machine lifecycle operations across the entire environment.

Libsoup: libsoup: heap buffer overflow from websocket pong signal type confusion
A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap corruption or a crash upon receiving a crafted Pong.

CWE-787 Sep 29, 2026
Rpm: rpm: integer overflow in iterreadarchivenext() leads to heap-based buffer overflow when parsing untrusted rpm packages
A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.

CWE-653 Sep 29, 2026
Flatpak: flatpak: sandboxed app can signal unsandboxed processes in the same process group
Flatpak's process ID namespace separation does not prevent a sandboxed app's kill(0, signal) or killpg(0, signal) calls from reaching processes outside the sandbox that share the same process group. A malicious or compromised Flatpak app can use this to cause denial of service by terminating processes outside its sandbox, such as the desktop shell.

CWE-61 Sep 29, 2026
Flatpak: flatpak: arbitrary write in root context via path traversal in deploy directory files/etc
A path traversal vulnerability in Flatpak's handling of the files/etc directory during app deployment allows a malicious Flatpak app to cause certain host system files (such as passwd, group, machine-id, or resolv.conf) to be emptied or replaced with a symlink when the app is installed or upgraded. In system-wide installations, the write is performed as root.

CWE-20 Sep 28, 2026
Flatpak: flatpak: denial of service via unsanitized keys in exported desktop entry / d-bus service files
Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit.

CWE-378 Sep 28, 2026
Flatpak: flatpak: world-writable temporary child repositories in system-helper cache path
Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted.

CWE-378 Sep 28, 2026
Flatpak: flatpak: world-readable oci authentication token in system-helper cache path
Flatpak writes the OCI repository authentication token with world-readable permissions (0644) in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only OCI-based sources (e.g. as used by Fedora) are affected; libostree-based sources such as Flathub are not.

CWE-825 Sep 28, 2026
Gcc-toolset-15-gcc: gcc: gcc-toolset-16: gcc: denial of service via use-after-free in binary heap erase_if
A flaw was found in GCC. When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption.

Streamshub/console: console-operator: streams for apache kafka console: unfiltered kafka client properties → sa-token exfiltration via config.providers
A flaw was found in the StreamsHub Console for Apache Kafka. Tenant-supplied Kafka client properties from the Console custom resource are copied into the console-api AdminClient configuration without filtering security-sensitive keys, allowing a Console CR author to set config.providers and bootstrap.servers to exfiltrate the console-api ServiceAccount token to an attacker-controlled broker.

CWE-829 Sep 28, 2026
Kube-compare: container:// reference extraction runs the image entrypoint and silently escalates to sudo
A flaw was found in kube-compare. When processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. This allows a remote attacker to achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges, posing a significant security risk.

CWE-770 Sep 28, 2026
Keycloak-services: keycloak-services: unbounded metric series creation via idp tag on broker login endpoint
A flaw was found in the Micrometer user-event metrics listener of Keycloak, a solution for integrated identity and access management. The issue occurs when the listener is configured to include the idp tag. An unauthenticated attacker can send requests to the identity broker login endpoint using arbitrary provider aliases, causing the system to create an unlimited number of metric time series. This can lead to excessive memory consumption and degrade the performance of both the server and its monitoring tools.

Noobaa-core: noobaa-core: os command injection in cluster_internal_api.set_hostname_internal
An OS command injection flaw was found in the set_hostname_internal function of NooBaa's cluster_internal_api. This component is responsible for managing the Multi-Cloud Object Gateway in OpenShift Data Foundation. The vulnerability occurs because the hostname parameter is passed directly to a shell command without proper sanitization. An authenticated attacker with administrative privileges can provide a specially crafted hostname containing shell metacharacters to execute arbitrary commands on the host system with the privileges of the NooBaa process.

Artemis-core-client: unsafe reflection in apache activemq artemis federation message deserialization
Apache ActiveMQ Artemis before 2.34.0 contains an unsafe reflection vulnerability in FederationStreamConnectMessage.getFederationPolicy(). The method calls Class.forName(clazz).getConstructor().newInstance() where clazz is read directly from the CORE protocol wire buffer without type validation. An authenticated federation peer can send a FEDERATION_DOWNSTREAM_CONNECT packet with a crafted class name, causing the broker to load and instantiate arbitrary classes visible to the Artemis module classloader. Static initializers (<clinit>) and no-argument constructors (<init>()) execute as side effects before the type cast, enabling denial of service via system-property poisoning, out-of-memory conditions via classloading, or broker state manipulation.

Flatpak: flatpak: extension metadata path traversal file existence oracle
A malicious Flatpak extension can probe the host filesystem to determine what files and directories exist at arbitrary paths, and host directory listings can be disclosed to sandboxed applications using the extension. Additionally, unvalidated extension metadata can cause extension content to be mounted at unintended locations inside the sandbox.

CWE-284 Sep 27, 2026
Flatpak: flatpak: unprivileged active user can bypass anti-downgrade checks for system apps/runtimes
On a multi-user system, a user with an active local login session could downgrade a system-wide Flatpak app to an older version by removing the app's remote ref via the unprivileged system-helper RemoveLocalRef method, causing the anti-downgrade check to fail to find a reference date. A malicious local user could use this to expose other users of the same system to an app version with unfixed vulnerabilities.

CWE-197 Sep 27, 2026
Flatpak: flatpak: buffer overflow in oci delta stream path names on 32-bit systems
The OCI delta stream parser read sizes as guint64 but passed them to GLib I/O and allocation functions expecting gsize (32 bits on 32-bit systems), causing undersized allocations while subsequent operations use the original 64-bit size, leading to heap buffer overflows. An attacker controlling an OCI registry can craft a delta stream that triggers this during flatpak install/update, potentially achieving code execution on 32-bit systems.

CWE-59 Sep 27, 2026
Flatpak: flatpak: path traversal issue in oci archive extraction via hardlinks
A malicious OCI registry can hardlink arbitrary host files into the extraction directory when a user installs or updates a Flatpak application from an OCI remote, allowing disclosure of arbitrary host file contents. For system-wide installs running as root, this includes sensitive files such as /etc/shadow.

Qemu-kvm: 9pfs: use-after-free race in tlcreate/twalk allows vm guest escape
A use-after-free vulnerability was found in QEMU's 9pfs subsystem. A race condition between the main thread and a worker thread when processing concurrent Tlcreate and Twalk requests allows a malicious guest user to craft a fid path containing stale heap data, bypassing directory traversal restrictions and escaping the shared directory boundary. This can lead to arbitrary host file read/write and code execution (VM escape) as the QEMU process user.

CWE-285 Sep 25, 2026
Keycloak-services: keycloak-services: fgap v2 composite-blind role mapping allows privilege escalation
A flaw was found in the Fine-Grained Admin Permissions (FGAP v2) feature of Keycloak, an identity and access management solution. The issue occurs when the system checks if a delegated administrator has permission to assign a specific role to a user. Because the check does not look inside composite roles to see what other permissions they contain, an administrator with limited rights can assign a role that secretly includes full administrative control. This allows the attacker to gain complete management access over the entire realm.

CWE-287 Sep 25, 2026
Keycloak-services: keycloak-services: standard token exchange v2 bypasses mtls holder-of-key binding
Keycloak provides a feature called mTLS holder-of-key binding which ensures that a token can only be used by the client that originally requested it by binding it to their digital certificate. A flaw was discovered where the new Standard Token Exchange V2 feature does not check for this certificate. This allows an attacker with stolen client credentials to obtain a standard, unrestricted token that bypasses these security protections.
