| CVE-2026-0965 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hummingbird and 1 more | 2026-05-19 | N/A |
| A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service (DoS) by causing the system to try and access dangerous files, such as block devices or large system files, which can disrupt normal operations. | ||||
| CVE-2026-0966 | 2 Libssh, Redhat | 6 Libssh, Enterprise Linux, Hardened Images and 3 more | 2026-05-19 | 8.2 High |
| A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to `SSH_LOG_PACKET (3)` or higher. Successful exploitation could lead to a self-Denial of Service of the per-connection daemon process. | ||||
| CVE-2026-0964 | 2 Libssh, Redhat | 6 Libssh, Enterprise Linux, Hardened Images and 3 more | 2026-05-19 | 6.3 Medium |
| A malicious SCP server can send unexpected paths that could make the client application override local files outside of working directory. This could be misused to create malicious executable or configuration files and make the user execute them under specific consequences. This is the same issue as in OpenSSH, tracked as CVE-2019-6111. | ||||
| CVE-2026-6473 | 2 Postgresql, Redhat | 2 Postgresql, Hummingbird | 2026-05-18 | 8.8 High |
| Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. | ||||
| CVE-2026-43512 | 2 Apache, Redhat | 2 Tomcat, Hummingbird | 2026-05-15 | 9.8 Critical |

Older unsupported versions any also be affect Users are recommended to upgrade to version 11.0.22, 10.1.55 or 9.0.118 which fix the issue. | ||||
| CVE-2026-6732 | 2 Redhat, Xmlsoft | 8 Enterprise Linux, Hardened Images, Hummingbird and 5 more | 2026-05-15 | 6.5 Medium |
| A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable. | ||||
| CVE-2025-14831 | 2 Red Hat, Redhat | 14 Enterprise Linux, Ai Inference Server, Ceph Storage and 11 more | 2026-05-14 | 5.3 Medium |
| A flaw was found in GnuTLS. This vulnerability allows a denial of service (DoS) by excessive CPU (Central Processing Unit) and memory consumption via specially crafted malicious certificates containing a large number of name constraints and subject alternative names (SANs). | ||||
| CVE-2026-7168 | 3 Curl, Haxx, Redhat | 3 Curl, Curl, Hummingbird | 2026-05-14 | 5.3 Medium |
| Successfully using libcurl to do a transfer over a specific HTTP proxy (`proxyA`) with **Digest** authentication and then changing the proxy host to a second one (`proxyB`) for a second transfer, reusing the same handle, makes libcurl wrongly pass on the `Proxy-Authorization:` header field meant for `proxyA`, to `proxyB`. | ||||
| CVE-2026-33813 | 2 Golang, Redhat | 2 Image, Hummingbird | 2026-05-13 | 7.5 High |
| Parsing a WEBP image with an invalid, large size panics on 32-bit platforms. | ||||
| CVE-2025-9820 | 1 Redhat | 8 Ceph Storage, Discovery, Enterprise Linux and 5 more | 2026-05-12 | 4 Medium |
| A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks. | ||||
| CVE-2025-7425 | 1 Redhat | 17 Cert Manager, Discovery, Enterprise Linux and 14 more | 2026-05-12 | 7.8 High |
| A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption. | ||||
| CVE-2025-6021 | 2 Redhat, Xmlsoft | 30 Discovery, Enterprise Linux, Enterprise Linux Eus and 27 more | 2026-05-12 | 7.5 High |
| A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input. | ||||
| CVE-2025-32989 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-05-12 | 5.3 Medium |
| A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly. | ||||
| CVE-2025-32988 | 2 Gnu, Redhat | 10 Gnutls, Ceph Storage, Discovery and 7 more | 2026-05-12 | 6.5 Medium |
| A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. | ||||
| CVE-2026-5435 | 3 Gnu, Redhat, The Gnu C Library | 3 Glibc, Hummingbird, Glibc | 2026-05-05 | 7.3 High |
| The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and can result in an out-of-bounds write when printing TSIG records. | ||||
| CVE-2026-6238 | 3 Gnu, Redhat, The Gnu C Library | 3 Glibc, Hummingbird, Glibc | 2026-05-04 | 6.5 Medium |
| The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to validate the RDATA content against the RDATA length in a DNS response when processing LOC, CERT, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory. These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions. | ||||
| CVE-2026-4426 | 2 Libarchive, Redhat | 6 Libarchive, Enterprise Linux, Hardened Images and 3 more | 2026-05-03 | 6.5 Medium |
| A flaw was found in libarchive. An Undefined Behavior vulnerability exists in the zisofs decompression logic, caused by improper validation of a field (`pz_log2_bs`) read from ISO9660 Rock Ridge extensions. A remote attacker can exploit this by supplying a specially crafted ISO file. This can lead to incorrect memory allocation and potential application crashes, resulting in a denial-of-service (DoS) condition. | ||||
| CVE-2026-5745 | 2 Libarchive, Redhat | 6 Libarchive, Enterprise Linux, Hardened Images and 3 more | 2026-05-03 | 5.5 Medium |
| A flaw was found in libarchive. A NULL pointer dereference vulnerability exists in the ACL parsing logic, specifically within the archive_acl_from_text_nl() function. When processing a malformed ACL string (such as a bare "d" or "default" tag without subsequent fields), the function fails to perform adequate validation before advancing the pointer. An attacker can exploit this by providing a maliciously crafted archive, causing an application utilizing the libarchive API (such as bsdtar) to crash, resulting in a Denial of Service (DoS). | ||||
| CVE-2026-1584 | 2 Gnu, Redhat | 5 Gnutls, Enterprise Linux, Hardened Images and 2 more | 2026-05-03 | 7.5 High |
| A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition. | ||||
| CVE-2026-2625 | 3 Redhat, Rust-rpm-sequoia, Sequoia-pgp | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-05-01 | 4 Medium |
| A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager (RPM) file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an unconditional termination of the rpm process. This issue results in an application level denial of service, making the system unable to process RPM files for signature verification. | ||||
