| CVE-2026-71225 | 2 Redhat, Smuellerdd | 8 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 5 more | 2026-10-22 | 6.5 Medium |
| A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs (over 64 KiB) in stateful modes such as Counter (CTR) or Cipher Block Chaining (CBC), the library improperly reuses the Initialization Vector (IV) for each internal data chunk. A remote attacker could potentially exploit this by making an application that uses libkcapi process specially crafted large inputs. This can lead to a significant weakening of data confidentiality, as the repeated IV use can expose relationships in encrypted plaintext, and may also affect data integrity by causing incorrect cryptographic processing. | ||||
| CVE-2026-5260 | 2 Gnu, Redhat | 16 Gnutls, Cert Manager, Discovery and 13 more | 2026-10-22 | 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-2026-58015 | 2 Gnome, Redhat | 17 Glib, Ai Inference Server, Cert Manager and 14 more | 2026-10-22 | 5.9 Medium |
| A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash. | ||||
| CVE-2026-58014 | 2 Gnome, Redhat | 17 Glib, Ai Inference Server, Cert Manager and 14 more | 2026-10-22 | 7.3 High |
| A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary. | ||||
| CVE-2026-92822 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Openshift | 2026-10-21 | 6.2 Medium |
| A flaw was found in libmodulemd. When parsing module metadata, the xmd field is converted into nested GVariant values through recursive YAML mapping and sequence helpers without a recursion-depth or node-count limit. An attacker who can supply crafted modulemd YAML with deeply nested xmd content can cause stack exhaustion or excessive resource consumption, resulting in a denial of service. | ||||
| CVE-2026-82327 | 1 Redhat | 8 Enterprise Linux, Hardened Images, Hummingbird and 5 more | 2026-10-21 | 5.5 Medium |
| A flaw was found in libsolv, a dependency-resolution library used by RPM-based package managers such as dnf and zypper to work with .solv repository cache files. When libsolv rewrites a .solv cache file, it reads directory-id values from the file's compressed filelist data without validating that they fall within the expected range. A corrupted or specially crafted .solv cache file (for example, one left in a torn state after an unclean system shutdown) can cause an out-of-bounds memory write when a tool such as dnf, yum, or zypper next processes it. Successful exploitation is expected to result in a crash of the affected tool (denial of service); it is not expected to allow arbitrary code execution because the out-of-bounds write always stores a fixed, non-attacker-controlled value. | ||||
| CVE-2026-111555 | 2 Luksmeta, Redhat | 4 Luksmeta, Enterprise Linux, Openshift and 1 more | 2026-10-21 | 6 Medium |
| A flaw was found in luksmeta. Improper boundary validation of metadata slots allows an attacker capable of supplying or modifying a disk header to redirect wipe or load operations outside the intended metadata area. An attacker could exploit this vulnerability by providing a crafted header with valid checksums to overwrite or zero out encrypted payload data, resulting in persistent data loss and corrupted storage. Exploitation typically requires privileged access to modify raw block devices or the ability to induce an administrator to process an untrusted disk image. | ||||
| CVE-2026-85977 | 2 Libtirpc Project, Redhat | 6 Libtirpc, Enterprise Linux, Hardened Images and 3 more | 2026-10-21 | 5.3 Medium |
| A flaw was found in libtirpc. A remote attacker can exploit this vulnerability by sending specially crafted PMAPPROC_DUMP replies to a client application that uses the pmap_getmaps() function against an attacker-controlled host. This unbounded decoding can lead to excessive memory and CPU allocation, causing the client process to experience a Denial of Service (DoS) due to resource exhaustion. | ||||
| CVE-2026-92982 | 1 Redhat | 10 Acm, Ansible Automation Platform, Container Native Virtualization and 7 more | 2026-10-21 | 8.5 High |
| A flaw was found in Ansible Operator Plugins. A low-privileged Kubernetes user can exploit a Jinja2 template injection vulnerability by crafting malicious custom resource (CR) specification values. These values are processed by Ansible without proper sanitization, allowing embedded Jinja2 expressions to be executed within the operator pod. This can lead to arbitrary code execution and privilege escalation, granting the attacker control over the operator's service account with cluster-wide permissions. | ||||
| CVE-2026-11332 | 1 Redhat | 20 Acm, Ansible Automation Platform, Ansible Automation Platform Developer and 17 more | 2026-10-21 | 7.8 High |
| A flaw was found in ansible-core. The ansible-galaxy role install command processes dependency specifications from a role's meta/requirements.yml file. Due to improper neutralization of argument delimiters, a malicious role author can inject arbitrary git configuration flags through the src field. This allows arbitrary code execution on the machine of a user who installs the role via ansible-galaxy role install. | ||||
| CVE-2026-89096 | 2 Nfs, Redhat | 4 Nfs-utils, Enterprise Linux, Openshift and 1 more | 2026-10-21 | 5.9 Medium |
| A flaw was found in nfs-utils. An unauthenticated remote attacker can trigger a Denial of Service (DoS) by sending repeated state notification requests to an exposed rpc.statd service. The service fails to properly release memory allocated during callback processing, leading to continuous memory growth. Sustained requests can exhaust system resources, eventually causing the service to degrade or crash. | ||||
| CVE-2026-16460 | 2 Bootc, Redhat | 6 Bootc, Enterprise Linux, Hardened Images and 3 more | 2026-10-21 | 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-2026-92823 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Openshift | 2026-10-21 | 6.2 Medium |
| A flaw was found in libmodulemd. In builds with rpmio support enabled, compressed modulemd YAML is decompressed through a custom read handler that does not enforce a cumulative decompressed-size limit before parsing. An attacker who can supply a highly compressible compressed YAML file can cause excessive CPU and memory consumption, resulting in a denial of service. | ||||
| CVE-2026-114236 | 1 Redhat | 19 Advanced Cluster Security, Ansible Automation Platform, Certifications and 16 more | 2026-10-21 | 3.3 Low |
| storage/pkg/archive.ApplyLayer and ApplyUncompressedLayer may, when processing corrupt or malicious inputs, leak a file descriptor; unbounded repeated calls can exhaust the process’ file descriptor limit | ||||
| CVE-2026-58224 | 2 Redhat, Samba | 5 Ceph Storage, Enterprise Linux, Openshift and 2 more | 2026-10-21 | 6.5 Medium |
| A flaw was found in Samba's CTDB, the clustered database service used by Samba. Insufficient integrity validation of received CTDB protocol packets allows malformed packets containing invalid field lengths, improperly terminated strings, or inconsistent packet sizes to be processed without adequate bounds checking. A remote attacker with access to the CTDB private network may trigger a denial of service through process crashes or excessive memory consumption and, in limited cases, disclose adjacent memory contents. | ||||
| CVE-2026-88252 | 3 Fedoraproject, Redhat, Sssd | 5 Sssd, Enterprise Linux, Openshift and 2 more | 2026-10-20 | 4.7 Medium |
| A flaw was found in sssd. A local user can cause a Denial of Service (DoS) by exhausting the responder service's available file descriptors (system handles used for open connections). By opening and maintaining many concurrent connections to a responder socket while continuing to queue new connection attempts, an attacker can trigger an unthrottled retry loop. This condition leads to high CPU utilization and stalls the service, preventing legitimate identity and authentication requests from being processed. | ||||
| CVE-2026-104795 | 1 Redhat | 1 Openshift | 2026-10-20 | 8.8 High |
| The insights-runtime-extractor runs as a privileged DaemonSet (`hostPID: true`) that scans container processes for runtime fingerprinting. When scanning a container, the coordinator: 1. **fork()s** a child process 2. **setns()** into the target container's PID and mount namespaces 3. **fchdir()** back to an orphaned FD pointing at the extractor's own root filesystem (where `/crio.sock` is hostPath-mounted) 4. Calls **only `seteuid(target_uid)`** — changing the effective UID but leaving the **real UID and saved-set-UID at 0** and **retaining the permitted capability set** 5. The `check_no_privileged_perms()` guard inspects only the Effective capability set (so it passes), and is **skipped entirely when the target runs as uid 0** 6. The `VersionExecutable` fingerprint invokes `fpr_kind_executable` with `process.command_line[0]` — the target's argv[0], read from `/proc/<pid>/cmdline` and **fully controlled by the workload** 7. `fpr_kind_executable` calls `exec.Command(executable, "--version").Output()` — executing the **workload's own binary** inside the workload's mount namespace while **ruid=0 in the host user namespace** The executed process can call `setuid(0)` to restore full root with `CAP_SYS_ADMIN`, and inherits the orphaned cwd which resolves into the extractor container's filesystem containing the host CRI-O socket. ## Affected Code ### 1. Insufficient privilege drop (Rust — extractor coordinator) **File:** `extractor/src/insights_runtime_extractor.rs` ```rust // Lines 139-146 — seteuid-only drop, guard skipped for root containers join_process_namespaces(process.pid)?; change_dir(current_dir); switch_user(*process.uid)?; if *process.uid != 0 { perms::check_no_privileged_perms() .expect("Must not have privileged permissions to run fingerprints"); } fingerprint::run_fingerprints(&config, out_dir, &process); ``` ```rust // Lines 182-185 — only effective UID changed; ruid/suid stay 0 fn switch_user(uid: u32) -> Result<(), ScannerError> { debug!("... Becoming user: {uid}"); seteuid(uid.into()).map_err(|e| ScannerError::Errno(e)) } ``` ### 2. Execution of untrusted binary (Go — fingerprint) **File:** `fingerprints/pkg/utils/file.go` ```go // Lines 75-80 — executes a path taken verbatim from workload's argv[0] func GetExecutableVersionOutput(executable string) (string, error) { out, err := exec.Command(executable, "--version").Output() if err != nil { return "", err } return string(out), nil } ``` ### 3. Workload-controlled path forwarded (Rust — version_executable) **File:** `version_executable.rs` ```rust // Lines 29-34 — workload-controlled command_line[0] forwarded to fingerprint return Some(vec![ fpr_kind_executable, out_dir.to_string(), String::from(&process.command_line[0]), String::from(&version_executable.runtime_kind_name), ]); ``` ## Attack Pattern **Attacker:** Any tenant able to schedule a pod (unprivileged, any namespace) **Victim:** The node running the insights-runtime-extractor DaemonSet **Trigger:** Automatic — the DaemonSet scans all container processes on the node **Attack sequence:** 1. Attacker creates a pod whose process name matches a configured versioned-executable pattern (`node`, `python`, `python3`, `MainThread`, or contains `java`) 2. The pod's main binary (at the path matching argv[0]) is a malicious executable that calls `setuid(0)` to restore root 3. When the insights operator triggers a scan, the DaemonSet forks, enters the attacker's mount namespace, and executes the attacker's binary with ruid=0 4. The attacker's code regains full root with `CAP_SYS_ADMIN` in the host user namespace 5. The inherited cwd contains the host CRI-O socket → full node compromise | ||||
| CVE-2026-86847 | 1 Redhat | 3 Enterprise Linux, Openshift, Openstack | 2026-10-20 | 6.5 Medium |
| A flaw was found in DPDK lib/vhost vhost-crypto. Write-back chain cleanup can follow an uninitialized next pointer when mapping a guest descriptor fails, causing the host vhost-crypto process to hang or crash. | ||||
| CVE-2026-89098 | 2 Nfs, Redhat | 4 Nfs-utils, Enterprise Linux, Openshift and 1 more | 2026-10-19 | 5.5 Medium |
| A flaw was found in nfs-utils. The fsidd daemon improperly handles input received over its local domain socket by relying on program assertions to verify command arguments. A local user can exploit this vulnerability by sending a malformed request lacking the required arguments to trigger an assertion failure. This causes the daemon to crash, resulting in a Denial of Service (DoS) for filesystem identifier lookup services until restarted. | ||||
| CVE-2024-2182 | 1 Redhat | 3 Enterprise Linux, Openshift, Openstack | 2026-10-19 | 6.5 Medium |
| A flaw was found in the Open Virtual Network (OVN). In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from inside unprivileged workloads, including virtual machines or containers, that can trigger a denial of service. | ||||
