CVE-2026-55654 3 Openbsd, Openssh, Redhat 9 Openssh, Openssh, Enterprise Linux and 6 more 2026-11-06 3.7 Low
A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service.
CVE-2026-5419 2 Gnu, Redhat 14 Gnutls, Cert Manager, Discovery and 11 more 2026-11-06 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-2026-3832 2 Gnu, Redhat 11 Gnutls, Cert Manager, Discovery and 8 more 2026-11-06 3.7 Low
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
CVE-2026-44605 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-11-06 5.5 Medium
A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable.
CVE-2026-3633 3 Gnome, Libsoup, Redhat 4 Libsoup, Libsoup, Enterprise Linux and 1 more 2026-11-06 3.9 Low
A flaw was found in libsoup. A remote attacker, by controlling the method parameter of the `soup_message_new()` function, could inject arbitrary headers and additional request data. This vulnerability, known as CRLF (Carriage Return Line Feed) injection, occurs because the method value is not properly escaped during request line construction, potentially leading to HTTP request injection.
CVE-2026-3632 3 Gnome, Libsoup, Redhat 4 Libsoup, Libsoup, Enterprise Linux and 1 more 2026-11-06 3.9 Low
A flaw was found in libsoup, a library used by applications to send network requests. This vulnerability occurs because libsoup does not properly validate hostnames, allowing special characters to be injected into HTTP headers. A remote attacker could exploit this to perform HTTP smuggling, where they can send hidden, malicious requests alongside legitimate ones. In certain situations, this could lead to Server-Side Request Forgery (SSRF), enabling an attacker to force the server to make unauthorized requests to other internal or external systems. The impact is low, as SoupServer is not actually used in internet infrastructure.
CVE-2026-123037 1 Redhat 12 Acm, Ansible Automation Platform, Ansible Core and 9 more 2026-11-06 6.7 Medium
A flaw was found in the ansible-core user module. When generate_ssh_key is enabled, User.ssh_key_gen() guards the key files against symlinks but checks the ~/.ssh directory only with os.path.exists(). An unprivileged user on a managed node who replaces their ~/.ssh with a symlink to an existing root-writable directory causes the privileged module to write the generated key pair through the symlink and then chown both files to that user. Because such files can be dropped into directories processed by schedulers (e.g. /etc/cron.daily) or dynamic MOTD (/etc/update-motd.d), the user can escalate to root on the managed node. This is an incomplete fix of CVE-2024-9902.
CVE-2026-3234 2 Apache, Redhat 3 Mod Proxy Cluster, Enterprise Linux, Jboss Core Services 2026-11-06 4.3 Medium
A flaw was found in mod_proxy_cluster. This vulnerability, a Carriage Return Line Feed (CRLF) injection in the decodeenc() function, allows a remote attacker to bypass input validation. By injecting CRLF sequences into the cluster configuration, an attacker can corrupt the response body of INFO endpoint responses. Exploitation requires network access to the MCMP protocol port, but no authentication is needed.
CVE-2026-3184 3 Kernel, Linux, Redhat 7 Util-linux, Util-linux, Enterprise Linux and 4 more 2026-11-06 3.7 Low
A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.
CVE-2026-28295 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 4.3 Medium
A flaw was found in the FTP GVfs backend. A malicious FTP server can exploit this vulnerability by providing an arbitrary IP address and port in its passive mode (PASV) response. The client unconditionally trusts this information and attempts to connect to the specified endpoint, allowing the malicious server to probe for open ports accessible from the client's network.
CVE-2026-2340 2 Redhat, Samba 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-11-06 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-2026-2708 3 Gnome, Libsoup, Redhat 4 Libsoup, Libsoup, Enterprise Linux and 1 more 2026-11-06 3.7 Low
A request smuggling vulnerability exists in libsoup's HTTP/1 header parsing logic. The soup_message_headers_append_common() function in libsoup/soup-message-headers.c unconditionally appends each header value without validating for duplicate or conflicting Content-Length fields. This allows an attacker to send HTTP requests containing multiple Content-Length headers with differing values.
CVE-2026-114232 2 Red Hat, Redhat 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more 2026-11-06 8.1 High
A flaw was found in the UserManagedPermissionService of the Keycloak authorization server. The UMA Protection API, which manages user permissions, fails to validate the resourceType field when a user creates a new policy. This allows an attacker to create a policy that applies to resources owned by other users, potentially leading to unauthorized access or modification of sensitive data across the entire realm.
CVE-2026-110932 2 Red Hat, Redhat 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more 2026-11-06 7.5 High
A flaw was found in the theme resource endpoint of Keycloak, an open-source identity and access management solution. The issue occurs because the server fails to validate theme names before using them as keys for an on-disk gzip cache. An unauthenticated attacker can exploit this by sending many requests with unique, fabricated theme names, leading to persistent disk space exhaustion that survives server restarts and causes service disruptions.
CVE-2026-2443 3 Gnome, Red Hat, Redhat 4 Libsoup, Enterprise Linux, Enterprise Linux and 1 more 2026-11-06 5.3 Medium
A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In certain build configurations, this could allow a remote attacker to access portions of server memory beyond the intended response. Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component.
CVE-2026-19411 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 3.9 Low
A NULL pointer vulnerability has been found in the the shim application of dp.c library. A missing NULL pointer could allow attackers to perform a denial of service attack on a system that uses shim application for UEFI bootloader.
CVE-2026-18839 2 Popt-devel, Redhat 8 Popt-static, Enterprise Linux, Hardened Images and 5 more 2026-11-06 2.2 Low
An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of service of the affected application.
CVE-2026-18743 2 Redhat, Rpm-software-management 8 Enterprise Linux, Hardened Images, Hummingbird and 5 more 2026-11-06 2.5 Low
A flaw was found in popt. This vulnerability allows an attacker to provide specially crafted configuration content to a host, which, when loaded, can lead to a small memory corruption issue. This occurs because of an error in how the `poptConfigFileToString` function reallocates memory for buffers. Successful exploitation could result in heap metadata corruption, potentially causing the affected process to become unavailable (denial of service).
CVE-2026-18739 2 Popt-devel, Redhat 6 Popt-static, Enterprise Linux, Hummingbird and 3 more 2026-11-06 2.5 Low
A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacker to execute arbitrary code if the host application then unsafely processes the altered data.
CVE-2026-18103 2 Dhcp-server, Redhat 3 Dhcp-server, Enterprise Linux, Rhel Els 2026-11-06 4.9 Medium
A flaw was found in dhcp-server. A remote attacker with network access to the OMAPI (Open Management Application Programming Interface) port, especially if not secured with TSIG (Transaction Signature) key authentication, could send a specially crafted lease creation request. This request, containing an overly long InfiniBand MAC address, triggers a buffer overflow in the `print_hw_addr()` function. Successful exploitation leads to a persistent denial of service (DoS), causing the `dhcpd` service to crash and preventing it from restarting without manual intervention.
