CVE-2026-112318 2 Red Hat, Redhat 7 Enterprise Linux, Enterprise Linux, Enterprise Linux Eus and 4 more 2026-11-13 6.5 Medium
The policy RPC stubs in kadmin/server/server_stubs.c in MIT Kerberos 5 (aka krb5) 1.5.3 and later do not reject a NULL policy name decoded by xdr_nullstring(), which allows remote authenticated users to cause a denial of service (kadmind crash via NULL pointer dereference) by sending a policy request with an empty policy name that reaches authorization checks or logging code.
CVE-2026-112316 2 Red Hat, Redhat 7 Enterprise Linux, Enterprise Linux, Enterprise Linux Eus and 4 more 2026-11-13 6.5 Medium
xdr_krb5_tl_data() in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) does not free partially decoded data on failure, which allows remote authenticated users to cause a denial of service (memory leak in kadmind) via crafted RPC requests that trigger a decode failure.
CVE-2026-112315 2 Red Hat, Redhat 7 Enterprise Linux, Enterprise Linux, Enterprise Linux Eus and 4 more 2026-11-13 5.3 Medium
The RPCSEC_GSS authentication routines in lib/rpc/authgss_prot.c in MIT Kerberos 5 (aka krb5) 1.4 and later do not free partially decoded buffers on failure, which allows remote attackers to cause a denial of service (memory leak in kadmind) via crafted RPCSEC_GSS messages.
CVE-2026-10609 1 Redhat 3 Cluster Logging Operator, Logging, Logging Subsystem For Red Hat Openshift 2026-11-13 6.8 Medium
A missing authorization flaw was found in the OpenShift Cluster Logging Operator. The operator creates and forwards ServiceAccount tokens to output destinations without verifying that the ClusterLogForwarder creator has permission to use those credentials, allowing a delegated editor to exfiltrate SA tokens and escalate privileges.
CVE-2026-92615 1 Redhat 4 Acm, Advanced Cluster Management For Kubernetes, Edge Manager and 1 more 2026-11-13 6.6 Medium
A flaw was found in flightctl. The configureRepoHTTPSClient() function in the device-render worker builds a per-repository tls.Config (which may include InsecureSkipVerify, a custom CA bundle, or tenant-supplied mTLS client certificates) and installs it into go-git's process-global client.Protocols map via gitclient.InstallProtocol("https", ...). Because the worker renders devices for multiple organizations concurrently from a shared goroutine pool, whichever tenant's repository configuration is written last wins for all in-flight git.Clone calls. This race condition can cause one tenant's TLS settings, including InsecureSkipVerify or mTLS client credentials, to leak into another tenant's git operations.
CVE-2026-13732 1 Redhat 13 Cost Management On Premise, Enterprise Linux, Enterprise Linux Eus and 10 more 2026-11-13 7 High
A flaw was found in GDB's STABS debug format parser. The read_member_functions() function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main function list while the list length counter is decremented, resulting in an out-of-bounds write when the function list is copied to its final allocated array. An attacker can craft an ELF binary with malicious .stab and .stabstr sections that triggers this out-of-bounds write when a user opens the file in GDB and performs any symbol-inspection operation such as setting a breakpoint. The inferior process does not need to be executed. Under controlled conditions, this was demonstrated to achieve execution of arbitrary commands within the GDB process.
CVE-2026-127101 3 Red Hat, Redhat, Sssd 6 Enterprise Linux, Enterprise Linux, Openshift and 3 more 2026-11-13 5.5 Medium
A flaw was found in SSSD's PAM responder. A local attacker can send an authentication request without first negotiating the client protocol version. The responder dereferences a NULL protocol-version pointer and crashes, disrupting SSSD-backed authentication. Repeated crafted requests can sustain the denial of service.
CVE-2026-128824 1 Redhat 2 Mirror Registry, Quay 2026-11-13 5.4 Medium
A flaw was found in Red Hat Quay. The v1 registry API error handler reflects the attacker-supplied image_id path segment in a response served as text/html, allowing a reflected cross-site scripting (XSS) attack. By tricking a user into visiting a specially crafted URL, a remote attacker can execute arbitrary JavaScript in the victim's browser within the Quay origin, potentially compromising the user's session.
CVE-2026-127030 3 Freeradius, Red Hat, Redhat 4 Freeradius, Enterprise Linux, Enterprise Linux and 1 more 2026-11-13 7.5 High
A flaw was found in freeradius. An improper length validation in the EAP-FAST module allows a stack-based buffer overflow during session ticket processing. A remote, unauthenticated attacker can exploit this flaw by sending a specially crafted handshake request, causing the server process to crash and resulting in a Denial of Service (DoS).
CVE-2026-128424 1 Redhat 1 Amq Streams 2026-11-13 5.3 Medium
A flaw was found in Kroxylicious. The ACL authorizer's rules-file parser unquotes `matching /…/` regular-expression literals using the string unquoting rules, which strips every backslash escape. As a result, an allow rule such as `matching /orders\.v1/` is compiled as the regex `orders.v1`, which also matches unintended names such as `ordersXv1`, and character classes such as `\d` and `\w` lose their special meaning. Allow rules written with regex escapes can therefore apply to more resources than the author intended. Depending on the ACL configuration, this may allow an authenticated Kafka client to access a resource (such as read or write a topic) that should have been denied.
CVE-2026-127099 3 Red Hat, Redhat, Sssd 6 Enterprise Linux, Enterprise Linux, Openshift and 3 more 2026-11-13 5.9 Medium
A flaw was found in SSSD's conversion of X.509 certificate RSA public keys to SSH keys. Missing size checks before copying RSA components into fixed-size stack buffers can cause a stack buffer overflow. An attacker able to supply a certificate with oversized RSA components that passes the configured certificate checks can cause denial of service and corrupt SSH responder memory.
CVE-2026-18379 2 Red Hat, Redhat 2 Enterprise Linux, Enterprise Linux 2026-11-13 8.8 High
A flaw was found in yggdrasil-worker-package-manager. An authenticated attacker can exploit this issue to achieve arbitrary file modification or potential privilege escalation. The vulnerability exists because repository management operations fail to sanitize directory traversal sequences (such as '../') within repository names. By supplying a crafted repository name, an attacker can manipulate the root-level worker process into creating or deleting files outside the intended directory, compromising host system integrity.
CVE-2026-126644 2 Red Hat, Redhat 2 Enterprise Linux, Enterprise Linux 2026-11-13 3.9 Low
A link-following flaw was found in the authorized_key module of the ansible.posix collection, residual to the fix for CVE-2026-11837. That fix guards only the final path component (os.chown with follow_symlinks=False and O_NOFOLLOW in _safe_open_write()). When an unprivileged local user replaces their ~/.ssh directory with a symlink to a directory they do not own, and an operator subsequently runs the authorized_key task as root (a common provisioning pattern), the module resolves its path operations through the symlink: atomic_move() writes the temporary file in the symlink target and renames it to <target>/authorized_keys, creating or overwriting a file in the attacker-chosen directory, and os.chmod(sshdir, 0o700) follows the symlink and changes the target directory's permissions. The written file is chowned to the unprivileged user, so this is not a privilege escalation, but it allows an attacker to create or overwrite files (for example in /etc/apt/apt.conf.d/, which APT reads regardless of file ownership) to cause integrity and availability impacts.
CVE-2026-121876 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Openshift and 2 more 2026-11-13 7.9 High
A flaw was found in the interaction between systemd-gpt-auto-generator and confidential computing guest VM images in OpenShift Sandboxed Containers (confidential peer pods). systemd-gpt-auto-generator automatically discovers and mounts GPT partitions by type GUID at boot with no user confirmation. In the confidential computing threat model, where the host/hypervisor is the adversary, a malicious host can inject partitions into the guest's virtual disk. Most critically, injecting a swap partition causes the guest kernel to page out TEE-encrypted memory to a host-controlled block device, breaking the confidentiality guarantee of the hardware TEE (AMD SEV-SNP, Intel TDX). The PodVM images use a GPT-partitioned disk with dm-verity on the root partition. However, the roothash= kernel parameter only disables root auto-discovery — non-root partitions (swap, /home, /var, /srv, /var/tmp) are still auto-discovered and mounted. The generator is shipped unmasked in the RHEL systemd-udev subpackage, and no kernel command line parameter in the measured UKI addon disables it. Additionally, the PodVM measurement script captures PCRs 3, 9, 11, and 12, but not PCR 5 (GPT partition table), so partition table modifications are not detected by remote attestation.
CVE-2026-115455 3 Gcc, Red Hat, Redhat 8 Gcc, Enterprise Linux, Enterprise Linux and 5 more 2026-11-13 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-2026-124745 3 Busybox, Red Hat, Redhat 6 Busybox, Enterprise Linux, Enterprise Linux and 3 more 2026-11-13 6.3 Medium
A flaw was found in BusyBox. When extracting an archive, the tar utility improperly resolves deferred hardlink targets across symbolic links pointing outside the intended extraction directory. An attacker could provide a specially crafted archive that links to sensitive files outside the extraction tree, allowing subsequent extraction operations to overwrite arbitrary files on the system.
CVE-2026-127029 3 Freeradius, Red Hat, Redhat 4 Freeradius, Enterprise Linux, Enterprise Linux and 1 more 2026-11-13 7.5 High
A flaw was found in freeradius's Extensible Authentication Protocol Method for Subscriber Identity Module (EAP-SIM) module. When handling authentication requests, the server copies a client-supplied identity into an internal structure without properly checking its length against a fixed-size buffer. An unauthenticated remote attacker can exploit this issue by sending specially crafted EAP-SIM messages, triggering a stack buffer overflow that crashes the service and results in a Denial of Service (DoS).
CVE-2026-127100 3 Red Hat, Redhat, Sssd 6 Enterprise Linux, Enterprise Linux, Openshift and 3 more 2026-11-13 5.5 Medium
A flaw was found in SSSD's PAM responder on builds with the JSON PAM extension enabled. A local attacker can submit a crafted authentication request containing a non-string OAuth2 code value. Missing JSON type validation leads to a NULL pointer dereference, terminating the PAM responder and disrupting SSSD-backed authentication.
CVE-2026-126831 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-13 5.5 Medium
A flaw was found in cpio. A local user can cause a Denial of Service (DoS) by triggering a stack-based buffer overflow when creating archives in tar or ustar formats. When archiving files owned by users or groups with names exceeding 32 characters, cpio copies these names into fixed-size memory without verifying their length. This unbounded copy corrupts stack memory and causes the application to crash.
CVE-2026-84503 1 Redhat 18 Acm, Ansible Automation Platform, Ansible Core and 15 more 2026-11-13 6.7 Medium
A flaw was found in ansible-core's ansible.builtin.git module. The module invokes git (ls-remote, clone, fetch) with the repository URL as a positional argument and without a "--" separator, so a repository URL that begins with a dash is interpreted by git as a command-line option. A caller that passes an attacker-controlled repository URL to the module can trigger argument injection (for example --upload-pack/--exec), resulting in arbitrary command execution on the host running the module.
