| CVE-2026-6245 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-04-15 | 5.5 Medium |
| A flaw was found in the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data is treated as a NUL-terminated C string without explicit termination, it results in an out-of-bounds read when processed by functions like snprintf(). A local attacker could potentially trigger this vulnerability by initiating a crafted passkey authentication request, causing the SSSD PAM responder to crash, resulting in a local Denial of Service (DoS). | ||||
| CVE-2025-49796 | 1 Redhat | 16 Cert Manager, Discovery, Enterprise Linux and 13 more | 2026-04-15 | 9.1 Critical |
| A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory. | ||||
| CVE-2025-14512 | 2 Gnome, Redhat | 4 Glib, Enterprise Linux, Hummingbird and 1 more | 2026-04-15 | 6.5 Medium |
| A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values. | ||||
| CVE-2026-1757 | 1 Redhat | 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more | 2026-04-15 | 6.2 Medium |
| A flaw was identified in the interactive shell of the xmllint utility, part of the libxml2 project, where memory allocated for user input is not properly released under certain conditions. When a user submits input consisting only of whitespace, the program skips command execution but fails to free the allocated buffer. Repeating this action causes memory to continuously accumulate. Over time, this can exhaust system memory and terminate the xmllint process, creating a denial-of-service condition on the local system. | ||||
| CVE-2025-14831 | 2 Red Hat, Redhat | 13 Enterprise Linux, Ai Inference Server, Ceph Storage and 10 more | 2026-04-15 | 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-2026-0992 | 1 Redhat | 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more | 2026-04-15 | 2.9 Low |
| A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition. | ||||
| CVE-2026-0989 | 1 Redhat | 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more | 2026-04-15 | 3.7 Low |
| A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk. | ||||
| CVE-2026-0990 | 1 Redhat | 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more | 2026-04-15 | 5.9 Medium |
| A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications. | ||||
| CVE-2026-0988 | 1 Redhat | 2 Enterprise Linux, Hummingbird | 2026-04-15 | 3.7 Low |
| A flaw was found in glib. Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS). | ||||
| CVE-2026-4111 | 1 Redhat | 8 Ai Inference Server, Discovery, Enterprise Linux and 5 more | 2026-04-15 | 7.5 High |
| A flaw was identified in the RAR5 archive decompression logic of the libarchive library, specifically within the archive_read_data() processing path. When a specially crafted RAR5 archive is processed, the decompression routine may enter a state where internal logic prevents forward progress. This condition results in an infinite loop that continuously consumes CPU resources. Because the archive passes checksum validation and appears structurally valid, affected applications cannot detect the issue before processing. This can allow attackers to cause persistent denial-of-service conditions in services that automatically process archives. | ||||
| CVE-2026-2100 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Openshift | 2026-04-15 | 5.3 Medium |
| A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states. | ||||
| CVE-2026-0966 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hummingbird and 1 more | 2026-04-15 | N/A |
| The API function `ssh_get_hexa()` is vulnerable, when 0-lenght input is provided to this function. This function is used internally in `ssh_get_fingerprint_hash()` and `ssh_print_hexa()` (deprecated), which is vulnerable to the same input (length is provided by the calling application). The function is also used internally in the gssapi code for logging the OIDs received by the server during GSSAPI authentication. This could be triggered remotely, when the server allows GSSAPI authentication and logging verbosity is set at least to SSH_LOG_PACKET (3). This could cause self-DoS of the per-connection daemon process. | ||||
| CVE-2026-0964 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hummingbird and 1 more | 2026-04-15 | N/A |
| 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-2026-0968 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hummingbird and 1 more | 2026-04-15 | 3.1 Low |
| A flaw was found in libssh in which a malicious SFTP (SSH File Transfer Protocol) server can exploit this by sending a malformed 'longname' field within an `SSH_FXP_NAME` message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap. This can cause unexpected behavior or lead to a denial of service (DoS) due to application crashes. | ||||
| CVE-2026-0967 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hummingbird and 1 more | 2026-04-15 | 5.5 Medium |
| A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion, resulting in a Denial of Service (DoS) for the client. | ||||
| CVE-2026-0965 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hummingbird and 1 more | 2026-04-15 | 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-2026-5121 | 2 Libarchive, Redhat | 6 Libarchive, Enterprise Linux, Hardened Images and 3 more | 2026-04-15 | 7.5 High |
| A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system. | ||||
| CVE-2026-2625 | 2 Redhat, Rust-rpm-sequoia | 3 Enterprise Linux, Hummingbird, Rust-rpm-sequoia | 2026-04-15 | 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. | ||||
| CVE-2026-1584 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Hummingbird and 1 more | 2026-04-15 | 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-2025-9900 | 1 Redhat | 10 Ai Inference Server, Discovery, Enterprise Linux and 7 more | 2026-04-15 | 8.8 High |
| A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user. | ||||
