| CVE-2026-55653 | 2 Openbsd, Redhat | 4 Openssh, Enterprise Linux, Hardened Images and 1 more | 2026-10-30 | 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-2026-71226 | 2 Redhat, Smuellerdd | 4 Enterprise Linux, Hardened Images, Openshift Container Platform and 1 more | 2026-10-30 | N/A | 7.3 HIGH |
| Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers. | |||||
| CVE-2026-28367 | 1 Redhat | 9 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 6 more | 2026-10-30 | N/A | 8.7 HIGH |
| A flaw was found in Undertow. A remote attacker can exploit this vulnerability by sending `\r\r\r` as a header block terminator. This can be used for request smuggling with certain proxy servers, such as older versions of Apache Traffic Server and Google Cloud Classic Application Load Balancer, potentially leading to unauthorized access or manipulation of web requests. | |||||
| CVE-2025-6170 | 2 Redhat, Xmlsoft | 4 Enterprise Linux, Jboss Core Services, Openshift Container Platform and 1 more | 2026-10-30 | 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-2026-58013 | 2 Gnome, Redhat | 2 Glib, Enterprise Linux | 2026-10-29 | N/A | 6.5 MEDIUM |
| A flaw was found in GLib. A buffer over-read can occur in g_io_channel_read_line_backend() in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes or a denial of service when the buffer over-read crosses a page boundary. | |||||
| CVE-2026-58012 | 2 Gnome, Redhat | 2 Glib, Enterprise Linux | 2026-10-29 | N/A | 6.5 MEDIUM |
| A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary. | |||||
| CVE-2026-58011 | 2 Gnome, Redhat | 2 Glib, Enterprise Linux | 2026-10-29 | N/A | 6.5 MEDIUM |
| A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service. | |||||
| CVE-2026-58010 | 2 Gnome, Redhat | 2 Glib, Enterprise Linux | 2026-10-29 | N/A | 6.5 MEDIUM |
| A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary. | |||||
| CVE-2026-102559 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-10-29 | N/A | 8.6 HIGH |
| A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow. | |||||
| CVE-2026-102558 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-10-29 | N/A | 8.6 HIGH |
| A flaw was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data. | |||||
| CVE-2026-102557 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-10-29 | N/A | 8.6 HIGH |
| A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used the full length, leading to heap corruption or a crash. | |||||
| CVE-2026-102556 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-10-29 | N/A | 8.6 HIGH |
| 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. | |||||
| CVE-2026-46300 | 3 Linux, Redhat, Siemens | 9 Linux Kernel, Enterprise Linux, Enterprise Linux Aus and 6 more | 2026-10-29 | N/A | 7.8 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: net: skbuff: preserve shared-frag marker during coalescing skb_try_coalesce() can attach paged frags from @from to @to. If @from has SKBFL_SHARED_FRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backed frags, but the shared-frag marker is currently lost. That breaks the invariant relied on by later in-place writers. In particular, ESP input checks skb_has_shared_frag() before deciding whether an uncloned nonlinear skb can skip skb_cow_data(). If TCP receive coalescing has moved shared frags into an unmarked skb, ESP can see skb_has_shared_frag() as false and decrypt in place over page-cache backed frags. Propagate SKBFL_SHARED_FRAG when skb_try_coalesce() transfers paged frags. The tailroom copy path does not need the marker because it copies bytes into @to's linear data rather than transferring frag descriptors. | |||||
| CVE-2026-5201 | 2 Gnome, Redhat | 18 Gdk-pixbuf, Ai Inference Server, Enterprise Linux and 15 more | 2026-10-29 | N/A | 7.5 HIGH |
| A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions. | |||||
| CVE-2026-49875 | 2 Apache, Redhat | 7 Cxf, Build Of Apache Camel, Enterprise Linux and 4 more | 2026-10-29 | N/A | 9.8 CRITICAL |
| Apache CXF's EndpointReferenceUtils and W3CMultiSchemaFactory classes construct a SAXParserFactory without the necessary JAXP hardening configurations, enabling out-of-band (OOB) external entity resolution. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue. | |||||
| CVE-2026-58016 | 2 Gnome, Redhat | 14 Glib, Cert-manager Operator, Codeready Linux Builder and 11 more | 2026-10-29 | N/A | 7.5 HIGH |
| A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service. | |||||
| CVE-2026-2100 | 2 P11-kit Project, Redhat | 7 P11-kit, Cert-manager Operator, Cost Management Metrics Operator and 4 more | 2026-10-29 | N/A | 5.3 MEDIUM |
| A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states. | |||||
| CVE-2026-37982 | 1 Redhat | 1 Build Of Keycloak | 2026-10-29 | N/A | 6.8 MEDIUM |
| A flaw was found in Keycloak. This authentication vulnerability allows a remote attacker to replay `ExecuteActionsActionToken` tokens within Keycloak's WebAuthn (Web Authentication) flow. By intercepting an execute-actions email link, an attacker can register their own authenticator to a victim's account. This leads to unauthorized enrollment of a hardware-backed credential, enabling persistent account takeover. | |||||
| CVE-2026-37979 | 1 Redhat | 1 Build Of Keycloak | 2026-10-29 | N/A | 6.5 MEDIUM |
| A flaw was found in Keycloak. This access control vulnerability in Keycloak's OpenID Connect (OIDC) token introspection endpoint allows a confidential client to bypass audience restrictions. An attacker-controlled client with valid credentials can retrieve sensitive token claims intended for other resource servers, compromising the confidentiality of lightweight access tokens. This issue can be exploited remotely by any confidential client in the realm with valid credentials. | |||||
| CVE-2024-3056 | 3 Fedoraproject, Podman Project, Redhat | 4 Fedora, Podman, Enterprise Linux and 1 more | 2026-10-29 | N/A | 7.7 HIGH |
| A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that, when configured to share the same IPC with at least one other container, can create a large number of IPC resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created are not. Those resources are tied to the IPC namespace that will not be removed until all containers using it are stopped, and one non-malicious container is holding the namespace open. The malicious container is restarted, either automatically or by attacker control, repeating the process and increasing the amount of memory consumed. With a container configured to restart always, such as `podman run --restart=always`, this can result in a memory-based denial of service of the system. | |||||
