| CVE-2026-4775 | 3 Debian, Libtiff, Redhat | 20 Debian Linux, Libtiff, Ai Inference Server and 17 more | 2026-10-26 | 7.8 High |
| A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution. | ||||
| CVE-2026-74860 | 1 Redhat | 11 Cert Manager, Cost Management On Premise, Enterprise Linux and 8 more | 2026-10-26 | 8.5 High |
| A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition (DTD) with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callback handler, where a string is freed twice. This flaw can lead to a denial of service (DoS) due to a reproducible crash in Python applications using the libxml2 SAX bindings. | ||||
| CVE-2026-78002 | 2 Redhat, Rsyslog | 7 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 4 more | 2026-10-26 | 7.5 High |
| A flaw was found in rsyslog. An unauthenticated remote attacker can trigger a heap buffer overflow in the RainerScript `replace()` function by sending specially crafted syslog messages. This vulnerability arises from an incorrect buffer size calculation during string replacement, causing memory corruption. Successful exploitation can lead to a denial of service (DoS) for the affected system. | ||||
| CVE-2026-96512 | 2 Redhat, Sudo Project | 9 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 6 more | 2026-10-26 | 7.8 High |
| A flaw was found in sudo. When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with timestamps that omit the trailing 'Z' timezone indicator, the time evaluation relies on the TZ environment variable inherited from the calling user. Because sudo is a setuid-root program, an unprivileged local user can set TZ to an extreme timezone offset to shift the authorization window by up to approximately 25 hours, causing expired rules to be treated as valid. This allows the user to execute commands outside the intended time window. Authentication is not bypassed; only the time-based authorization check is affected. | ||||
| CVE-2026-11861 | 2 Freeipa, Redhat | 8 Freeipa, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-10-26 | 9.6 Critical |
| A flaw was found in FreeIPA. When a trust relationship is configured between FreeIPA and Active Directory, Active Directory users can bypass authentication for FreeIPA services, including the portal, SMB server, and LDAP directory. This is possible by impersonating a client name in the Ticket Granting Service (TGS) due to FreeIPA services not verifying Privilege Attribute Certificate (PAC) certificates. This vulnerability could allow an authenticated Active Directory user to escalate their privileges within the FreeIPA domain. | ||||
| CVE-2026-79678 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Freeipa and 5 more | 2026-10-26 | 8.1 High |
| A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion. | ||||
| CVE-2026-76578 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Freeipa and 5 more | 2026-10-26 | 9.8 Critical |
| A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services. | ||||
| CVE-2026-73198 | 2 Freeipa, Redhat | 8 Freeipa, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-10-26 | 7.5 High |
| A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition. | ||||
| CVE-2026-73197 | 2 Freeipa, Redhat | 8 Freeipa, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-10-26 | 7.5 High |
| A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service. | ||||
| CVE-2026-19550 | 2 Freeipa, Redhat | 8 Freeipa, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-10-26 | 8.2 High |
| A flaw was found in FreeIPA. The trust-fetch-domains command is gated by a read-only permission on the trust object rather than a trust-administration permission, allowing an authenticated, non-privileged IPA user to trigger a privileged Active Directory trust refresh using an attacker-supplied server and credentials, resulting in unauthorized, attacker-controlled modification of trusted-domain and ID-range identity data in the IPA LDAP directory. | ||||
| CVE-2026-18147 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Freeipa and 5 more | 2026-10-26 | 8.1 High |
| A flaw was found in FreeIPA. An unauthenticated remote attacker could exploit a DOM Cross-Site Scripting (XSS) vulnerability in the FreeIPA/IdM Web UI password reset page. By enticing a victim to click a specially crafted link and complete a password reset, the attacker could inject and execute arbitrary JavaScript code. This allows the attacker to perform actions within the victim's authenticated session, potentially leading to full administrative control if an IdM administrator is targeted. | ||||
| CVE-2026-13097 | 2 Freeipa, Redhat | 8 Freeipa, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-10-26 | 8.7 High |
| A privilege escalation flaw was found in FreeIPA. The uniqueness constraint enforced on Kerberos principal name attributes in the 389-ds directory server does not properly account for equivalent representations of the same principal name, allowing a user with sufficient LDAP write privileges to create a service principal that impersonates an existing privileged one. This can lead to unauthorized acquisition of Kerberos service tickets for sensitive services, potentially resulting in full domain compromise. | ||||
| CVE-2026-83596 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-10-26 | 8.8 High |
| A flaw was found in WebKitGTK. Processing malicious web content can cause memory corruption due to improper memory handling. | ||||
| CVE-2026-78376 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-10-26 | 8.8 High |
| A flaw was found in WebKitGTK. Processing malicious web content can cause a use-after-free issue due to improper memory handling and result in memory corruption. | ||||
| CVE-2026-114406 | 1 Redhat | 13 Advanced Cluster Security, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-10-26 | 6.8 Medium |
| The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed. | ||||
| CVE-2026-55655 | 3 Openbsd, Openssh, Redhat | 12 Openssh, Openssh, Enterprise Linux and 9 more | 2026-10-26 | 5 Medium |
| A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session. | ||||
| CVE-2026-55653 | 3 Openbsd, Openssh, Redhat | 12 Openssh, Openssh, Enterprise Linux and 9 more | 2026-10-26 | 4.3 Medium |
| A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS). | ||||
| CVE-2026-96280 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Eus | 2026-10-26 | 7.5 High |
| The OCI delta stream parser read sizes as guint64 but passed them to GLib I/O and allocation functions expecting gsize (32 bits on 32-bit systems), causing undersized allocations while subsequent operations use the original 64-bit size, leading to heap buffer overflows. An attacker controlling an OCI registry can craft a delta stream that triggers this during flatpak install/update, potentially achieving code execution on 32-bit systems. | ||||
| CVE-2026-96275 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Eus | 2026-10-26 | 8.8 High |
| A malicious or compromised Flatpak repository can write attacker-controlled content to arbitrary locations on the host filesystem via extract_extra_data(). On system installs, the write happens as root. Two issues combine: `files/extra` is resolved via path operations that follow symlinks, and blob names from `xa.extra-data-sources` are not sanitized against `..` traversal. | ||||
| 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. | ||||
