CVE-2026-96280 2 Flatpak, Redhat 4 Flatpak, Enterprise Linux, Rhel E4s and 1 more 2026-10-27 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 4 Flatpak, Enterprise Linux, Rhel E4s and 1 more 2026-10-27 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-2026-4775 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-2026-11861 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-2026-55655 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-2026-71227 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-2026-58015 2 Gnome, Redhat 17 Glib, Ai Inference Server, Cert Manager and 14 more 2026-10-22 5.9 Medium
A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash.
CVE-2026-19654 2 Redhat, Rsyslog 7 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 4 more 2026-10-21 7.5 High
A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module. A crafted input sequence during oversize-frame recovery can cause an invalid internal message length and terminate rsyslogd. No confidentiality or integrity impact, privilege escalation, or code execution has been identified. imtcp and the default imptcp framing modes are not affected.
