| CVE-2026-4480 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-07-24 | N/A | 9.0 CRITICAL |
| A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the "print command" setting via the "%J" substitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system. | |||||
| CVE-2026-58015 | 2 Gnome, Redhat | 2 Glib, Enterprise Linux | 2026-07-23 | N/A | 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-2026-9064 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-07-23 | N/A | 7.5 HIGH |
| A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, worker thread starvation, or out-of-memory termination, resulting in a denial of service. | |||||
| CVE-2026-8830 | 1 Redhat | 1 Build Of Keycloak | 2026-07-23 | N/A | 4.3 MEDIUM |
| A flaw was found in Keycloak. An authenticated user can bypass configured WebAuthn policies during credential registration by manipulating client-side JavaScript. This occurs because the server-side processAction() fails to validate that the newly created credential's parameters, such as public key algorithms, match the realm's configured WebAuthn policies. This could lead to the creation of credentials that do not adhere to administrative security requirements, potentially weakening the overall security posture of the system by allowing non-compliant authentication methods. | |||||
| CVE-2000-0963 | 4 Freebsd, Immunix, Invisible-island and 1 more | 4 Freebsd, Immunix, Ncurses and 1 more | 2026-07-23 | 7.2 HIGH | N/A |
| Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFO_DIRS. | |||||
| CVE-2002-0062 | 5 Debian, Freebsd, Invisible-island and 2 more | 5 Debian Linux, Freebsd, Ncurses and 2 more | 2026-07-23 | 7.2 HIGH | N/A |
| Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling." | |||||
| CVE-2026-42010 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Hardened Images and 1 more | 2026-07-23 | N/A | 7.1 HIGH |
| A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process. | |||||
| CVE-2026-42009 | 2 Gnu, Redhat | 14 Gnutls, Enterprise Linux, Enterprise Linux For Els and 11 more | 2026-07-23 | N/A | 7.5 HIGH |
| A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service. | |||||
| CVE-2026-9087 | 1 Redhat | 1 Build Of Keycloak | 2026-07-23 | N/A | 6.4 MEDIUM |
| A flaw was found in Keycloak. The cross-session verification proof is keyed only by (local userId, idpAlias) and is not bound to the upstream identity that was actually verified, so a second upstream account on the same IdP can consume it and get linked to the victim's local account. | |||||
| CVE-2026-8922 | 1 Redhat | 1 Build Of Keycloak | 2026-07-23 | N/A | 5.4 MEDIUM |
| A flaw was found in Keycloak. When both realm-level and client-level `notBefore` revocation policies are configured, Keycloak's OpenID Connect (OIDC) Introspection feature fails to properly honor the realm-level policy. This allows tokens that should have been revoked to remain active, potentially leading to unauthorized access or continued session validity. This could impact the security of systems utilizing Keycloak for identity and access management. | |||||
| CVE-2026-54230 | 3 Abrt Project, Fedoraproject, Redhat | 3 Abrt, Fedora, Enterprise Linux | 2026-07-23 | N/A | 7.0 HIGH |
| A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary file overwrites on the system. | |||||
| CVE-2026-54231 | 3 Abrt Project, Fedoraproject, Redhat | 3 Abrt, Fedora, Enterprise Linux | 2026-07-23 | N/A | 5.5 MEDIUM |
| A content injection vulnerability was found in the ABRT post-create event handler scripts in libreport. The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded control characters. A local user can inject arbitrary content into the journal output by embedding newline characters in syslog messages, controlling the content that root writes to dump directory files. | |||||
| CVE-2026-41731 | 2 Redhat, Vmware | 3 Fuse, Jboss Enterprise Application Platform Expansion Pack, Spring For Apache Kafka | 2026-07-23 | N/A | 8.1 HIGH |
| JsonKafkaHeaderMapper and the deprecated DefaultKafkaHeaderMapper matched type headers against trusted packages using a prefix check, meaning that trusting any package implicitly trusted all of its subpackages. Combined with Jackson's default bean deserialization, a producer could supply crafted header values that caused the consumer to deserialize arbitrary JDK types. Affected versions: Spring for Apache Kafka 4.0.0 through 4.0.5; 3.3.0 through 3.3.15; 3.2.0 through 3.2.13; 2.9.0 through 2.9.13; 2.8.0 through 2.8.11. | |||||

| 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 | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-07-23 | N/A | 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-2026-11786 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-07-23 | N/A | 1.9 LOW |
| A flaw was found in 389 Directory Server. The LDIF parser reads past the end of a heap buffer when processing attribute types with trailing semicolons during database import, causing an out-of-bounds read detectable under memory instrumentation. | |||||
| CVE-2026-11793 | 1 Redhat | 1 389 Directory Server | 2026-07-23 | N/A | 4.9 MEDIUM |
| A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix() function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory Manager privileges can crash the LDAP server by storing a crafted credential with an oversized algorithm ID. FORTIFY_SOURCE mitigates this to denial of service only. | |||||
| CVE-2026-11785 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-07-23 | N/A | 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-2026-11787 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-07-23 | N/A | 5.0 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-2026-11790 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-07-23 | N/A | 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. | |||||
