CVE-2026-71227 2 Redhat, Smuellerdd 8 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 5 more 2026-10-22 5.1 Medium
A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected application or thread unresponsive.
CVE-2026-71226 2 Redhat, Smuellerdd 8 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 5 more 2026-10-22 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-2026-71225 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-2026-82327 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-2026-93017 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-21 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 2026-10-21 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-2026-89096 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-2026-16487 2 Bootc, Redhat 4 Bootc, Enterprise Linux, Hardened Images and 1 more 2026-10-21 8.1 High
Red Hat Product Security has determined that this is not a vulnerability in bootc or containers-common. bootc fetches images under /etc/containers/policy.json. The shipped default is insecureAcceptAnything for registries without an explicit signature requirement; registry.redhat.io and registry.access.redhat.com require signatures. Updating a mutable tag requires the ability to publish to the reference an administrator has already configured the host to follow. Requiring signatures is available through that policy and through bootc enforce-container-sigpolicy, which is off by default. Persistence of /var across bootc rollback is expected image-mode behavior.
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-2026-58224 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-2026-110924 2 Openssh, Redhat 4 Openssh, Enterprise Linux, Hardened Images and 1 more 2026-10-21 4.8 Medium
CVE-2026-110924 has been marked as a duplicate of CVE-2026-106553.
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-2026-89098 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-2026-104040 3 Fedoraproject, Redhat, Sssd 5 Sssd, Enterprise Linux, Openshift and 2 more 2026-10-16 4.4 Medium
A flaw was found in SSSD. When configured with the Entra ID identity provider, input lookup names containing single quotes are not properly escaped before being included in Microsoft Graph Open Data Protocol (OData) queries. A low-privileged local user can exploit this flaw by submitting a crafted search request, altering query filters to broaden user or group searches. This can lead to information disclosure by retrieving unintended directory objects, as well as a Denial of Service (DoS) through excessive processing and cache population.
CVE-2026-104037 2 Redhat, Sssd 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-10-16 5.5 Medium
A flaw was found in SSSD. A local attacker can exploit this issue by sending a specially crafted request with an invalid packet length to the autofs responder UNIX socket. This causes an integer underflow and an out-of-bounds memory read, which can crash the responder process and result in a denial of service (DoS).
CVE-2026-75939 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-15 7.4 High
A flaw was found in openshift/oc-mirror. The tool incorrectly verifies PGP (Pretty Good Privacy) release image signatures by checking for signature errors before the entire signed body is processed, leading to a bypass of the signature verification. A remote attacker, by intercepting or manipulating network traffic to the signature endpoint, could exploit this to craft a PGP message with a valid Red Hat release key ID but a forged signature. This enables the `oc-mirror` tool to accept and mirror a malicious release payload into a disconnected registry, potentially compromising the integrity of software deployments.
CVE-2026-49329 1 Redhat 2 Openshift, Openshift Container Platform 2026-10-15 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.
