CVE-2026-42011 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-10-30 7.4 High
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
CVE-2026-5260 2 Gnu, Redhat 16 Gnutls, Cert Manager, Discovery and 13 more 2026-10-30 8.2 High
A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure.
CVE-2026-109971 2 Red Hat, Redhat 4 Enterprise Linux, Enterprise Linux, Openshift and 1 more 2026-10-30 4.7 Medium
A flaw was found in the clevis PKCS#11 pin. The clevis-decrypt-pkcs11 script passes the PKCS#11 token PIN as a command-line argument to pkcs11-tool, making it visible to any local user through process listing or the /proc filesystem.
CVE-2026-109970 2 Red Hat, Redhat 4 Enterprise Linux, Enterprise Linux, Openshift and 1 more 2026-10-30 4.7 Medium
A flaw was found in the clevis PKCS#11 pin. The clevis-luks-pkcs11-askpin script writes the PKCS#11 token PIN in plaintext to a file without setting restrictive permissions. Under the default process umask, the file is world-readable. Additionally, the PIN file is not reliably cleaned up if the decryption script exits early, leaving the PIN accessible indefinitely.
CVE-2026-109969 2 Red Hat, Redhat 4 Enterprise Linux, Enterprise Linux, Openshift and 1 more 2026-10-30 4.7 Medium
A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon creates AF_UNIX sockets without explicit permission restrictions or peer credential verification. Under a permissive process umask, any local user can connect to the control socket and inject arbitrary device/key pairs, or connect to the data socket to receive LUKS passphrases.
CVE-2026-109968 2 Red Hat, Redhat 4 Enterprise Linux, Enterprise Linux, Openshift and 1 more 2026-10-30 5.5 Medium
A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon logs LUKS disk encryption passphrases in plaintext to a log file. The log file is created without restrictive permissions, making it world-readable under the default process umask. A local attacker can read the log file to obtain the LUKS passphrase.
CVE-2026-42012 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-10-30 7.1 High
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information.
CVE-2026-92824 2 Red Hat, Redhat 6 Enterprise Linux, Enterprise Linux, Hardened Images and 3 more 2026-10-30 6.2 Medium
A flaw was found in libmodulemd. In the module stream v2 rpm-map emission path, an inner loop incorrectly uses the count of digest algorithms as its bound instead of the number of checksums in the current digest table. Crafted modulemd v2 metadata with multiple digest types can trigger an out-of-bounds read during YAML serialization, typically causing a crash and resulting in a denial of service.
CVE-2026-76781 1 Redhat 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more 2026-10-30 5.5 Medium
A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a `nextCatalog` element lacks its mandatory `catalog` attribute, leading to the application crashing and causing a Denial of Service (DoS).
CVE-2026-95619 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-10-30 7.7 High
A flaw was found in libstdc++. An integer overflow can occur when processing large inputs to the aligned operator new in the C++ library. This vulnerability could lead to an undersized memory allocation, potentially causing memory corruption or application instability.
CVE-2026-94640 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-10-30 7.5 High
A flaw was found in rpcbind. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a large number of unique requests. The rpcbind service records previously unseen RPC (Remote Procedure Call) statistics in unbounded in-memory lists, leading to persistent memory growth and increased CPU usage. This can degrade or exhaust service availability.
CVE-2026-92574 2 Red Hat, Redhat 5 Enterprise Linux, Confidential Compute Attestation, Enterprise Linux and 2 more 2026-10-30 8.8 High
A vulnerability in CRI-O checkpoint restore allows a user who can create a pod from a malicious checkpointed container to bypass the destination Kubernetes security context. The restored process may retain credentials, Linux capabilities, no_new_privs, and seccomp state from the checkpoint instead of enforcing the destination configuration. This can allow execution with elevated privileges across the container security boundary. Affected upstream supported versions are CRI-O 1.34 and later. Downstream Red Hat products are affected from OCP 4.17 onward. Fixes have been applied to supported branches but are not yet released. Exploitation requires permission to create a pod from a malicious checkpoint image and checkpoint restore functionality to be available.
CVE-2026-93017 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-30 7.7 High
The `insights-operator-gather` ClusterRole grants the operator's service account read access to secrets in the core API group with no namespace or resourceNames restriction — therefore, access to every secret in every namespace in the cluster. Ref: https://github.com/openshift/insights-operator/blob/8f15e3157ff09f54ab22801f5b21da35a195cc6d/manifests/03-clusterrole.yaml#L368-L373 ``` - apiGroups: - "" resources: - secrets verbs: - get - list ``` By spawning a pod with the gather service account mounted, an attacker will be able to access any secret in any namespace. ``` spec: serviceAccountName:"gather" ```
CVE-2026-75888 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-30 7.7 High
A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetch arbitrary URLs, potentially leading to the disclosure of sensitive information through error messages or enabling blind port scanning within the cluster.
CVE-2026-49329 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-30 7.5 High
A flaw was found in openshift/oauth-server. The OAuth login and error page endpoints pass the unauthenticated Accept-Language header to golang.org/x/text/language.ParseAcceptLanguage() without input validation. A bypass of the CVE-2022-32149 mitigation exists: the upstream guard counts only '-' characters but the internal BCP 47 scanner aliases '_' to '-' after the guard check. An unauthenticated attacker can send a crafted Accept-Language header using '_' separators to trigger quadratic-time parsing, consuming excessive CPU and denying authentication to all cluster users.
CVE-2026-43961 2 Redhat, Vim 5 Enterprise Linux, Hummingbird, Openshift and 2 more 2026-10-30 7.8 High
A flaw was found in Vim's netrw plugin. A crafted filename containing quote characters and expression fragments can break out of the quoted context during mark/unmark operations, allowing arbitrary Vimscript execution. This can be leveraged to run shell commands with the privileges of the user running Vim.
CVE-2026-15801 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-30 8 High
A vulnerability was found in CRI-O related to the container checkpoint and restore feature. When CRI-O is configured to restore containers from checkpoint archives, insufficient validation of restore metadata may allow a user with sufficient privileges to perform unintended operations on the host filesystem. Successful exploitation requires that container checkpoint and restore functionality is enabled, which is not the default configuration. An attacker must also be able to trigger restoration of a container from untrusted checkpoint content.
CVE-2026-46300 3 Linux, Redhat, Siemens 10 Kernel, Linux Kernel, Enterprise Linux and 7 more 2026-10-29 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-2026-104030 3 Fedoraproject, Redhat, Sssd 5 Sssd, Enterprise Linux, Openshift and 2 more 2026-10-28 5.5 Medium
A flaw was found in sssd. This vulnerability allows a local user to cause a Denial of Service (DoS) by submitting a specially crafted passkey authentication token that lacks null terminators. The authentication service reads past the end of the provided memory buffer, causing the process to crash and disrupting authentication services.
CVE-2026-104031 4 Fedoraproject, Red Hat, Redhat and 1 more 6 Sssd, Enterprise Linux, Enterprise Linux and 3 more 2026-10-28 5.5 Medium
A flaw was found in SSSD. In configurations where the autofs responder service is enabled, memory allocated during successful request processing is not released until the client connection terminates. A local attacker can exploit this vulnerability by maintaining an open connection and repeatedly submitting valid requests, leading to memory exhaustion and a Denial of Service (DoS).
