| CVE-2026-115486 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-05 | 7.1 High |
| A flaw was found in the iscsiuio component of open-iscsi. The IPv6 Neighbor Discovery handler accesses link-layer address options at a fixed offset without verifying the packet contains them. Additionally, the ARP table is updated unconditionally with attacker-controlled addresses from the packet headers. An attacker on the same network segment can send a minimal Neighbor Advertisement to poison the ARP table and redirect network traffic. | ||||
| CVE-2026-115485 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-05 | 6.3 Medium |
| A flaw was found in the iscsiuio component of open-iscsi. The DHCPv6 option parser calls strlen() on raw network data without ensuring a NUL terminator is present, causing it to read past the buffer into heap memory. This can result in a daemon crash, a 1-byte heap overwrite, or corruption of the iSCSI initiator name. An attacker on the same network segment can trigger this by sending a crafted DHCPv6 Advertise message. | ||||
| CVE-2026-115484 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-05 | 7.6 High |
| A flaw was found in the iscsiuio component of open-iscsi. The DHCPv4 option parser incorrectly calculates the length of the options data, causing it to read beyond the allocated buffer into adjacent heap memory. An attacker on the same network segment can send a crafted DHCP response to crash the daemon or corrupt its network configuration. | ||||
| CVE-2026-115455 | 3 Gcc, Red Hat, Redhat | 8 Gcc, Enterprise Linux, Enterprise Linux and 5 more | 2026-11-05 | 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-2026-11884 | 1 Redhat | 4 Directory Server, Enterprise Linux, Redhat Directory Server and 1 more | 2026-11-05 | 6.5 Medium |
| A heap buffer overflow flaw was found in 389 Directory Server. When serializing objectclass definitions, the oc_superior (SUP) field length is omitted from buffer size calculations in read_schema_dse() and schema_oc_to_string(), but the field is still written via strcat(). An attacker with Directory Manager privileges, or a compromised replication supplier, can trigger a server crash by creating objectclasses with long SUP values. This is an incomplete fix variant of CVE-2025-14905. | ||||
| CVE-2026-11861 | 2 Freeipa, Redhat | 9 Freeipa, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-11-05 | 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-2026-11873 | 1 Redhat | 4 Certificate System, Dogtag Certificate System, Enterprise Linux and 1 more | 2026-11-05 | 6.5 Medium |
| An Apache-proxied Dogtag CA REST endpoint exposed by IdM (POST /ca/rest/certrequests) returns HTTP 500 with internal Java stack traces for unauthenticated malformed requests. The same unauthenticated error path emits large multi-line stack traces into the CA debug log, creating a log-amplification resource exhaustion vector (disk growth and I/O contention) without requiring authentication. | ||||
| CVE-2026-11850 | 1 Redhat | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-11-05 | 5 Medium |
| An integer underflow vulnerability was found in MIT krb5 in the berval2tl_data() function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c. The function performs an unsigned subtraction (bv_len - 2) without a prior bounds check. When bv_len is 0 or 1, the subtraction wraps to a large value which is then truncated to uint16_t, yielding 0xFFFE (65534) or 0xFFFF (65535). The subsequent malloc succeeds and memcpy reads up to 65534 bytes from a 0-1 byte buffer, resulting in a heap out-of-bounds read. The attack vector involves a malicious or compromised LDAP KDB backend returning a krbExtraData attribute with bv_len < 2, triggering the underflow when the KDC or kadmind reads principal data. | ||||
| CVE-2026-11820 | 1 Redhat | 2 Community.general, Enterprise Linux | 2026-11-05 | 6.5 Medium |
| A flaw was found in the community.general Ansible collection's nexmo module. The module constructs HTTP requests to the Vonage/Nexmo SMS API by encoding API credentials (api_key and api_secret) into URL query parameters and sending them via GET requests. This causes credentials to be exposed in web server access logs, proxy logs, HTTP Referer headers, and network monitoring tools, despite the Ansible argument specification marking these parameters as no_log. An attacker with access to any of these logging or monitoring points can obtain the full API credentials and gain unauthorized access to the victim's Vonage/Nexmo account. | ||||
| CVE-2026-11819 | 1 Redhat | 2 Community.general, Enterprise Linux | 2026-11-05 | 5.5 Medium |
| Module: plugins/modules/keyring_info.py CVSS 3.1: 5.5 MEDIUM — AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N Issue: The module retrieves a passphrase from the OS native keyring (GNOME Keyring, macOS Keychain, Windows Credential Manager) and places it directly into result["passphrase"] with no output suppression, no no_log protection, and no documentation warning. Root Cause: Line 105 (protected): keyring_password=dict(type="str", required=True, no_log=True) Line 127 (NOT protected): result["passphrase"] = passphrase Observed Output: { "changed": false, "passphrase": "MyMasterP@ssw0rd!SSH_Key_Secret" } Visible via register + debug: { "keyring_result": { "changed": false, "passphrase": "MyMasterP@ssw0rd!SSH_Key_Secret" } } Impact: Master passwords, SSH key passphrases and service credentials appear in all Ansible output register: keyring_result followed by debug: var=keyring_result prints passphrase in full Ansible fact caching backends (Redis, JSON file, memcached) may persist the passphrase AWX/Tower job logs silently store the live credential Fix: module.exit_json(changed=False, passphrase=passphrase, _ansible_no_log=True) Also add a documentation warning requiring callers to use no_log: true at the task level. PoCs Fig 1: PoC execution showing passphrase in plaintext output Fig 2: Source code showing no_log=True on input (line 105) vs unprotected output (line 127) | ||||
| CVE-2026-11791 | 1 Redhat | 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more | 2026-11-05 | 5 Medium |
| A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator triggers schema reload while concurrent LDAP query traffic is active, worker threads may access freed memory, resulting in use-after-free or double-free and a denial of service (server crash). | ||||
| CVE-2026-11790 | 1 Redhat | 5 389 Directory Server, Directory Server, Enterprise Linux and 2 more | 2026-11-05 | 4.9 Medium |
| A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password storage plugin does not enforce an upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user's password hash can cause excessive CPU consumption during authentication, resulting in denial of service. | ||||
| CVE-2026-11789 | 1 Redhat | 5 389 Directory Server, Directory Server, Enterprise Linux and 2 more | 2026-11-05 | 4.9 Medium |
| A flaw was found in 389 Directory Server. The SMD5 password storage plugin performs unsigned integer underflow when computing salt length from a crafted password hash shorter than 16 bytes, causing a buffer over-read that crashes the LDAP server during authentication. | ||||
| CVE-2026-11788 | 1 Redhat | 12 389 Directory Server, Directory Server, Directory Server E4s and 9 more | 2026-11-05 | 5.9 Medium |
| A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure. | ||||
| CVE-2026-11787 | 1 Redhat | 5 389 Directory Server, Directory Server, Enterprise Linux and 2 more | 2026-11-05 | 5 Medium |
| A flaw was found in 389 Directory Server. The ldap_utf8prev() function reads bytes before the start of a buffer without bounds checking, causing a heap buffer over-read in string filter parsing that may influence internal filter processing behavior. | ||||
| CVE-2026-11785 | 1 Redhat | 5 389 Directory Server, Directory Server, Enterprise Linux and 2 more | 2026-11-05 | 4.3 Medium |
| A flaw was found in 389 Directory Server. A type confusion in the SSO token extended operation handler causes partial stack address information to be disclosed in LDAP responses to authenticated users. | ||||
| CVE-2026-11770 | 2 Port389, Redhat | 13 389-ds-base, 389 Directory Server, Directory Server and 10 more | 2026-11-05 | 7.5 High |
| A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information. | ||||
| CVE-2026-11611 | 1 Redhat | 5 389 Directory Server, Directory Server, Enterprise Linux and 2 more | 2026-11-05 | 6.5 Medium |
| A flaw was found in 389 Directory Server. The Content Synchronization persistent search plugin allows unbounded memory growth when an authenticated client stops reading sync responses, enabling denial of service. Additional race conditions in plugin thread lifecycle can cause crashes during connection teardown or shutdown. | ||||
| CVE-2026-50633 | 2 Apache, Redhat | 3 Cxf, Build Of Apache Camel, Fuse | 2026-11-05 | 8.1 High |
| A JNDI Injection vulnerability has been discovered in Apache CXF's JCA integration module, which can allow for code execution, if an attacker is able to manipulate the JCA deployment descriptor (ra.xml) or runtime activation parameters. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue. | ||||
| CVE-2026-110777 | 3 Gnome, Red Hat, Redhat | 4 Evolution-data-server, Enterprise Linux, Enterprise Linux and 1 more | 2026-11-05 | 5.7 Medium |
| A flaw was found in evolution-data-server. Calendar events containing a file:// URI in their ATTACH property automatically read the targeted local file, base64-encode its contents and upload it back to the server when the event is saved. There are no file path restrictions or checks to verify whether the attachment originally came from the server or was added locally. This allows an attacker with access to a shared CalDAV calendar to exfiltrate arbitrary files the user has access to when interacting with malicious calendar events. | ||||
