CVE-2023-6563 1 Redhat 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more 2026-09-22 7.7 High
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2026-16517 2 Libarchive, Redhat 6 Libarchive, Enterprise Linux, Hardened Images and 3 more 2026-09-21 2.9 Low
A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption.
CVE-2026-75885 1 Redhat 2 Openshift, Openshift Container Platform 2026-09-21 9.3 Critical
A flaw was found in the OpenShift console. Unauthenticated access to the `/api/devfile/` and `/api/devfile/samples/` endpoints allows a remote attacker to send crafted devfile payloads. This can lead to Server-Side Request Forgery (SSRF), where the console pod makes requests to internal services and reflects partial responses to the attacker. Additionally, by sending repeated large requests without a specified content length, an attacker can cause unbounded memory growth, leading to a Denial of Service (DoS).
CVE-2026-76781 1 Redhat 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more 2026-09-21 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-2026-92574 2 Red Hat, Redhat 5 Enterprise Linux, Confidential Compute Attestation, Enterprise Linux and 2 more 2026-09-21 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-2026-6862 2 Redhat, Ubuntu 5 Enterprise Linux, Hummingbird, Openshift and 2 more 2026-09-21 5.5 Medium
A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI (Extensible Firmware Interface) device path node header. A local user could exploit this vulnerability by providing a specially crafted device path node. This can lead to infinite recursion, causing stack exhaustion and a process crash, resulting in a denial of service (DoS).
CVE-2026-81665 2 Corosync, Redhat 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more 2026-09-21 7.5 High
A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.
CVE-2026-71226 2 Redhat, Smuellerdd 7 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 4 more 2026-09-21 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 7 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 4 more 2026-09-21 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-2026-87876 2 Openprinting, Redhat 6 Cups, Enterprise Linux, Hardened Images and 3 more 2026-09-21 3 Low
Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations.
CVE-2026-42965 1 Redhat 3 Openshift, Openshift Container Platform, Openshift Router 2026-09-21 7.7 High
A flaw was found in the OpenShift Router. A user with EndpointSlice write access can exploit this vulnerability by creating a Service backed by an FQDN (Fully Qualified Domain Name) EndpointSlice that resolves to a cloud metadata endpoint. This allows the router to proxy requests to the cloud metadata endpoint, leading to the disclosure of instance credentials and other sensitive metadata. This bypasses previous security measures for validating IP addresses.
CVE-2026-43961 2 Redhat, Vim 5 Enterprise Linux, Hummingbird, Openshift and 2 more 2026-09-21 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-2026-81627 2 Qemu, Redhat 8 Qemu, Enterprise Linux, Enterprise Linux For Nvidia 26 and 5 more 2026-09-21 8.2 High
A flaw was found in QEMU. The VAPIC setup hypercall in hw/i386/vapic.c does not validate that the writable RAM alias remains within the option ROM window. A privileged guest user on a Q35/KVM machine can position this alias over locked SMRAM, bypassing chipset D_LCK protection and injecting code into System Management Mode memory.
CVE-2026-42784 3 Red Hat, Redhat, Sequoia-pgp 12 Enterprise Linux, Ansible Automation Platform, Confidential Compute Attestation and 9 more 2026-09-21 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-2026-15816 1 Redhat 12 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 9 more 2026-09-21 7.5 High
A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.
CVE-2026-6893 1 Redhat 13 Dracut, Enterprise Linux, Enterprise Linux Eus and 10 more 2026-09-21 7.5 High
A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior.
CVE-2026-48864 2 Opensuse, Redhat 21 Libsolv, Discovery, Enterprise Linux and 18 more 2026-09-17 7.8 High
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
CVE-2026-3833 2 Gnu, Redhat 15 Gnutls, Discovery, Enterprise Linux and 12 more 2026-09-17 6.5 Medium
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-2340 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-09-17 6.5 Medium
A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file.
CVE-2026-42010 2 Gnu, Redhat 15 Gnutls, Ai Inference Server, Discovery and 12 more 2026-09-17 7.1 High
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
