CVE-2026-18147 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Freeipa and 6 more 2026-11-04 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-2026-16529 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 7.5 High
A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet reads.
CVE-2026-16527 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 7.3 High
An unauthenticated remote attacker can bypass access controls by sending crafted requests to the PCP pmproxy /store endpoint. This allows the attacker to overwrite any PMDA metric, leading to arbitrary code execution and system takeover.
CVE-2026-16526 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 8.8 High
A flaw in the PCP linux_sockets module exposes an unsecured internal connection. An attacker with initial code execution can exploit this to escalate privileges and execute arbitrary commands as root.
CVE-2026-16524 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 7.8 High
A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.
CVE-2026-1933 2 Redhat, Samba 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-11-04 7.1 High
A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.
CVE-2026-1761 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more 2026-11-04 8.6 High
A flaw was found in libsoup. This stack-based buffer overflow vulnerability occurs during the parsing of multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this by sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may result in application crashes or arbitrary code execution in applications that process untrusted server responses, and it does not require authentication or user interaction.
CVE-2026-13097 2 Freeipa, Redhat 9 Freeipa, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 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-2026-12912 2 Libtiff, Redhat 12 Libtiff, Enterprise Linux, Enterprise Linux Eus and 9 more 2026-11-04 7.3 High
A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).
CVE-2026-16313 1 Redhat 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-11-04 7.6 High
A flaw was found in sg3_utils. The sg_inq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev device database. This could allow an attacker who can present a crafted SCSI device to execute arbitrary commands as root when the device is disconnected.
CVE-2026-15722 1 Redhat 12 389 Directory Server, Directory Server, Directory Server E4s and 9 more 2026-11-04 7.5 High
A stack buffer overflow flaw was found in 389 Directory Server (389-ds-base). The get_ruvelement_from_berval() function in repl5_ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP server by sending a crafted StartNSDS50ReplicationRequest extended operation containing a replica ID field with more than 16 digit characters. The overflow occurs during payload decoding, before any authorization check. Stack protectors limit impact to denial of service.
CVE-2026-14474 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift and 6 more 2026-11-04 8.8 High
A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts.
CVE-2026-114406 1 Redhat 24 Advanced Cluster Security, Agentic Cluster Security Suite, Ai Inference Server and 21 more 2026-11-04 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-2026-11837 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Openstack and 5 more 2026-11-04 7.3 High
A local privilege escalation vulnerability was found in the ansible.posix authorized_key module. The module's keyfile() function uses os.chown() instead of os.lchown() and opens files without O_NOFOLLOW when managing SSH authorized keys. An unprivileged local user can pre-stage symbolic links in their ~/.ssh directory to redirect file ownership changes to arbitrary system paths when an operator runs the authorized_key task as root, leading to local privilege escalation.
CVE-2026-11774 1 Redhat 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more 2026-11-04 7.6 High
An integer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), adding sizeof(uint32_t) to a crafted SASL packet length prefix of 0xFFFFFFFC causes unsigned wraparound to zero, bypassing the nsslapd-maxsasliosize limit and leading to a heap buffer overflow of up to approximately 2 megabytes of attacker-controlled data. After a successful SASL bind with integrity protection (SSF > 0), a remote attacker can cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE). In FreeIPA and Red Hat Identity Management deployments, any domain user with a valid Kerberos ticket, enrolled host, or service account can trigger this vulnerability over the network. This flaw is independent of CVE-2025-14905, which patched schema.c only and did not modify sasl_io.c.
CVE-2026-11610 1 Redhat 10 Directory Server, Directory Server E4s, Enterprise Linux and 7 more 2026-11-04 8.8 High
A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). After a successful SASL bind with integrity protection (SSF > 0), an authenticated attacker can send a specially crafted oversized LDAP UNBIND packet that is copied into a 512-byte heap receive buffer without a bounds check in sasl_io_recv() in sasl_io.c. This allows up to approximately 2 megabytes of attacker-controlled data to overflow the buffer, causing a denial of service (server crash). In FreeIPA and Red Hat Identity Management deployments, any domain user with a valid Kerberos ticket, any enrolled host, or any service account can trigger this vulnerability over the network after authenticating via GSSAPI. The vulnerable code path has existed since approximately 2013 (389-ds-base 1.3.2) and was not addressed by the CVE-2025-14905 fix, which patched a separate heap overflow in schema.c only.
CVE-2026-0719 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more 2026-11-04 8.6 High
A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk.
CVE-2026-102560 3 Gnome, Libsoup, Redhat 7 Libsoup, Libsoup, Enterprise Linux and 4 more 2026-11-04 8.6 High
A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.
CVE-2026-102559 3 Gnome, Libsoup, Redhat 10 Libsoup, Libsoup, Enterprise Linux and 7 more 2026-11-04 8.6 High
A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow.
CVE-2026-102557 3 Gnome, Libsoup, Redhat 10 Libsoup, Libsoup, Enterprise Linux and 7 more 2026-11-04 8.6 High
A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used the full length, leading to heap corruption or a crash.
