CVE-2026-16460 2 Bootc, Redhat 6 Bootc, Enterprise Linux, Hardened Images and 3 more 2026-11-04 7.4 High
A flaw was found in bootc and ostree. Already-staged deployments are finalized without revalidating the deployment's container image against the current containers signature policy. Unsigned OS content staged under a prior permissive policy can remain bootable after policy is hardened to reject unsigned images, leading to full host compromise on reboot.
CVE-2026-12610 3 Fedoraproject, Redhat, Sssd 7 Sssd, Enterprise Linux, Hardened Images and 4 more 2026-11-04 6.4 Medium
A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that disrupts authentication. This vulnerability also presents a potential for privilege escalation, although it is difficult to exploit.
CVE-2026-115455 3 Gcc, Red Hat, Redhat 7 Gcc, Enterprise Linux, Enterprise Linux and 4 more 2026-11-04 6.5 Medium
A flaw was found in GCC libstdc++. When an application extracts data into a bitset from a wide-character stream, internal stack memory allocation fails to properly account for character size and alignment. An attacker capable of supplying crafted input to an affected application could trigger a stack-based buffer overflow leading denial of service (DoS).
CVE-2026-54099 1 Redhat 5 Openshift, Openshift Container Platform, Openshift For Windows Containers and 2 more 2026-11-04 8.8 High
A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. The WICD CSR auto-approver validates that a Certificate Signing Request contains the organization system:wicd-nodes but does not reject additional organization values such as system:masters. A compromised Windows worker node that holds WICD credentials can submit a CSR that is auto-approved and signed by the cluster, yielding a client certificate that grants cluster-administrator privileges and enabling full cluster takeover.
CVE-2026-42784 3 Red Hat, Redhat, Sequoia-pgp 14 Enterprise Linux, Ansible Automation Platform, Ansible Automation Platform Developer and 11 more 2026-11-04 7.4 High
A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity.
CVE-2026-74860 1 Redhat 16 Cert Manager, Cost Management On Premise, Enterprise Linux and 13 more 2026-11-04 8.5 High
A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition (DTD) with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callback handler, where a string is freed twice. This flaw can lead to a denial of service (DoS) due to a reproducible crash in Python applications using the libxml2 SAX bindings.
CVE-2026-93009 3 Dnsmasq, Red Hat, Redhat 8 Dnsmasq, Enterprise Linux, Ceph Storage and 5 more 2026-11-04 4.3 Medium
A flaw was found in dnsmasq. The DHCPv6 client hostname parser can read one byte past the end of a crafted FQDN option because it checks the next label length before confirming the pointer is still inside the option. An attacker on the local network can trigger this with a single DHCPv6 packet. The extra byte is not returned to the client or logged, and no crash has been demonstrated.
CVE-2026-104039 3 Fedoraproject, Redhat, Sssd 5 Sssd, Enterprise Linux, Openshift and 2 more 2026-11-03 4.7 Medium
A flaw was found in SSSD. A local user can cause a denial of service (DoS) by disrupting system authentication services. When handling Generic Security Services Application Programming Interface (GSSAPI) authentication in the Pluggable Authentication Module (PAM) responder, cached connection state is freed upon completion without clearing the reference pointer. An attacker can exploit this by sending an additional request over the same connection, causing the service to access invalid memory and unexpectedly terminate.
CVE-2026-114038 2 Red Hat, Redhat 4 Enterprise Linux, Enterprise Linux, Openshift and 1 more 2026-11-03 5.1 Medium
A flaw was found in device-mapper-multipath. A local user can trigger an out-of-bounds read by sending a command with a format string ending in a trailing percent character to the multipath daemon. This issue can allow the user to expose unintended daemon memory, leading to information disclosure, or cause the daemon to crash, resulting in a Denial of Service (DoS).
CVE-2026-5419 2 Gnu, Redhat 13 Gnutls, Cert Manager, Discovery and 10 more 2026-11-03 3.7 Low
A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure.
CVE-2026-18107 1 Redhat 3 Enterprise Linux, Openshift, Openshift Container Platform 2026-11-03 7.8 High
A flaw was found in CRIU's handling of restartable sequences (rseq) during checkpoint/restore. A malicious process inside a container can register an rseq critical section that hijacks CRIU's parasite code injection during checkpoint, allowing it to spoof the process credentials saved in the checkpoint image. On restore, the container process gains elevated capabilities and zeroed UIDs/GIDs. The practical impact on Red Hat products is limited by several factors: checkpoint/restore requires root privileges (podman) or cluster-admin RBAC (OpenShift) to trigger and cannot be initiated from within the container itself; on OpenShift prior to 4.17 the feature required explicit opt-in, and on 4.17+ the kubelet checkpoint API RBAC is not configured by default; OpenShift enforces user namespaces by default for regular workloads (hostUsers is gated behind admin-only SCCs), which makes the spoofed capabilities namespace-scoped and ineffective for privilege escalation; SELinux type enforcement (container_t) blocks privilege transitions independently of capabilities; seccomp filters persist through checkpoint/restore and cannot be corrupted via the parasite; and kernel mount namespace ownership checks on RHEL 9/10 kernels prevent mount-based container escape even with spoofed capabilities.
CVE-2026-86566 3 Dpdk, Red Hat, Redhat 6 Dpdk, Enterprise Linux, Enterprise Linux and 3 more 2026-11-03 6.5 Medium
A flaw was found in DPDK lib/vhost. A guest with runt RX descriptors can underflow the copy length in vhost enqueue, causing a denial of service in a shared vhost backend such as OVS-DPDK.
CVE-2026-86561 3 Dpdk, Red Hat, Redhat 8 Dpdk, Enterprise Linux, Enterprise Linux and 5 more 2026-11-03 6.5 Medium
A flaw was found in DPDK lib/vhost. Memory size is not adequately validated before mmap during vhost memory-region setup, which can lead to a host crash or memory corruption.
CVE-2026-86567 3 Dpdk, Red Hat, Redhat 8 Dpdk, Enterprise Linux, Enterprise Linux and 5 more 2026-11-03 8.8 High
A flaw was found in DPDK lib/vhost. The VDUSE handler fails to invalidate vring pointers when the IOTLB is invalidated, leading to use-after-unmap.
CVE-2026-86565 3 Dpdk, Red Hat, Redhat 8 Dpdk, Enterprise Linux, Enterprise Linux and 5 more 2026-11-03 8.2 High
A flaw was found in DPDK lib/vhost. A guest can desynchronize virtqueue size from inflight descriptor table size, causing an out-of-bounds write in the host vhost process.
CVE-2026-86563 3 Dpdk, Red Hat, Redhat 8 Dpdk, Enterprise Linux, Enterprise Linux and 5 more 2026-11-03 7.8 High
A flaw was found in DPDK lib/vhost. A double-offset bug in vhost log mapping calculation can lead to incorrect memory access.
CVE-2026-81666 2 Corosync, Redhat 4 Corosync, Enterprise Linux, Openshift and 1 more 2026-11-03 6.5 Medium
An integer overflow was found in Corosync's handling of membership commit token messages. The length-validation check for these messages can be bypassed on 32-bit systems due to an integer overflow in the calculation of the expected message length, allowing a crafted network packet to trigger an out-of-bounds memory access that crashes the Corosync daemon. This results in a denial of service for the affected cluster node. The overflow does not occur on 64-bit systems, where the length calculation is correctly performed in 64-bit arithmetic.
CVE-2026-42015 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-11-03 5.3 Medium
A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts.
CVE-2026-42014 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-11-03 6.6 Medium
A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path.
CVE-2026-120194 3 Json-glib, Red Hat, Redhat 5 Json-glib, Enterprise Linux, Enterprise Linux and 2 more 2026-11-03 7.5 High
A flaw was found in json-glib. The JSONPath slice evaluator used by json_path_query() can enter an infinite loop when given a slice expression with a negative step. An application that evaluates attacker-controlled JSONPath expressions can be forced into a hang, leading to a denial of service.
