| CVE-2026-97025 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 3.2 Low |
| 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. | ||||
| CVE-2026-97027 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 3.6 Low |
| 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. | ||||
| CVE-2026-96284 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 2.5 Low |
| A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control. | ||||
| CVE-2026-95520 | 1 Redhat | 2 Enterprise Linux, Hummingbird | 2026-09-29 | 7.1 High |
| 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. | ||||
| CVE-2026-97029 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-29 | 5.7 Medium |
| 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. | ||||
| CVE-2026-96541 | 2 Gnome, Redhat | 2 Gnome-remote-desktop, Enterprise Linux | 2026-09-28 | 7.5 High |
| A denial-of-service flaw was found in gnome-remote-desktop. An unauthenticated remote attacker can open RDP connections without completing the handshake and retain the connection-throttling slots indefinitely because no pre-authentication handshake deadline is enforced. By exhausting the global connection limit, an attacker can prevent new RDP clients from connecting until a holding socket is closed. | ||||
| CVE-2026-95519 | 2 Redhat, Rpm | 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more | 2026-09-28 | 7.8 High |
| A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using `rpm -q -p` or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the `rpm` process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account. | ||||
| CVE-2026-95521 | 2 Redhat, Rpm | 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more | 2026-09-28 | 7.8 High |
| A command injection flaw was found in rpm. Installing or rebuilding a source RPM whose source or spec file basenames contain a %() macro construct causes rpm to execute an attacker-controlled shell command via popen() while relocating the source file list. This allows arbitrary command execution as the invoking (typically non-root) user, simply by installing, rebuilding, or otherwise processing an untrusted .src.rpm. | ||||
| CVE-2026-96279 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-28 | 6.5 Medium |
| 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. | ||||
| CVE-2026-96283 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-28 | 3.3 Low |
| By calling org.freedesktop.Flatpak.SystemHelper.CancelPull on another user's pull, the pull is not actually cancelled but removed from internal tracking, making it impossible for the owning user to stop it. Ongoing pulls cannot be stopped. | ||||
| CVE-2026-96282 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-28 | 3.1 Low |
| 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. | ||||
| CVE-2026-43958 | 1 Redhat | 4 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 1 more | 2026-09-28 | 7.8 High |
| A flaw was found in rrdcached, a component of rrdtool. A local attacker with access to a rrdcached socket can exploit a stack-based buffer overflow by sending an oversized CREATE request. This vulnerability can lead to a denial of service by crashing the daemon or potentially allow for arbitrary code execution, impacting the integrity and confidentiality of data. | ||||
| CVE-2026-96276 | 2 Flatpak, Redhat | 2 Flatpak, Enterprise Linux | 2026-09-27 | 6.5 Medium |
| If a malicious SDK container declares an extension point with a crafted `directory` path, and a developer runs `flatpak build-init --writable-sdk --sdk-extension` with that SDK, attacker-chosen files could be written outside the working directory, since the target path is resolved via a function that allows `..` traversal. | ||||
| CVE-2026-2604 | 2 Gnome, Redhat | 2 Evolution-data-server, Enterprise Linux | 2026-09-25 | 5.6 Medium |
| A flaw was found in evolution-data-server. Inconsistent comparison logic in the addressbook file backend allows a Flatpak application with D-Bus access to craft a malicious URI containing directory traversal sequences. This URI is stored without proper validation during contact creation or modification. Later, during contact deletion, the URI is processed with a less strict check, leading to the deletion of arbitrary files on the host filesystem. This could potentially include critical Flatpak override files. | ||||
| CVE-2026-88264 | 2 Containers, Redhat | 5 Crun, Enterprise Linux, Hardened Images and 2 more | 2026-09-25 | 5.6 Medium |
| A flaw was found in crun. When the container configuration does not give /dev a dedicated mount, terminal setup can redirect /dev/console onto an attacker-controlled path, including via the read-only-rootfs bind-mount fallback. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed release is available yet. | ||||
| CVE-2026-96546 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-09-25 | 2.5 Low |
| A one-byte out-of-bounds heap read flaw was found in GIMP's uncompressed DDS image loader. When a user opens an uncompressed DDS image, the file-dds plug-in performs an unconditional one-byte look-ahead after processing the final pixel. This may cause the plug-in to crash if the byte immediately following the pixel buffer is inaccessible; no information disclosure or code execution has been demonstrated. | ||||
| CVE-2026-10805 | 1 Redhat | 14 Enterprise Linux, Hummingbird, Jboss Enterprise Application Platform Expansion Pack and 11 more | 2026-09-25 | 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-2026-93433 | 1 Redhat | 1 Enterprise Linux | 2026-09-24 | 5.5 Medium |
| A flaw was found in libstoragemgmt. An attacker with control over a local or virtual storage device could provide specially crafted SCSI (Small Computer System Interface) Vital Product Data (VPD) page 0x80 data. This malformed data, specifically an untrusted page length field, can lead to a stack buffer overflow in the `_sg_parse_vpd_80()` function during serial number parsing. Successful exploitation could result in a denial of service by crashing or destabilizing the process querying the serial number. | ||||
| CVE-2026-15711 | 2 Libsoup, Redhat | 8 Libsoup, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-09-24 | 7.5 High |
| A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames (e.g., PING, PONG, CLOSE) contain a payload of 125 bytes or less. A remote, unauthenticated attacker can exploit this by sending a non-compliant, oversized control frame. Because the parser handles this protocol violation improperly instead of throwing an immediate connection termination error, it triggers a internal processing crash, resulting in a remote denial of service (DoS) for applications utilizing libsoup WebSockets. | ||||
| CVE-2026-15709 | 2 Libsoup, Redhat | 8 Libsoup, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-09-24 | 7.5 High |
| A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop (inflate()) processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via max_incoming_payload_size, it fails to track or limit memory allocation during decompression. A separate check for decompressed size (max_total_message_size) exists but executes only after inflation is complete, and it is entirely disabled by default for client connections. A remote, unauthenticated attacker can exploit this by sending a small, highly compressed payload (a decompression bomb), causing unbounded memory allocation that triggers an Out-of-Memory (OOM) crash and a Denial of Service (DoS). | ||||
