CVE-2026-3184 3 Kernel, Linux, Redhat 6 Util-linux, Util-linux, Enterprise Linux and 3 more 2026-05-01 3.7 Low
A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.
CVE-2026-4105 1 Redhat 4 Enterprise Linux, Hummingbird, Openshift and 1 more 2026-04-30 6.7 Medium
A flaw was found in systemd. The systemd-machined service contains an Improper Access Control vulnerability due to insufficient validation of the class parameter in the RegisterMachine D-Bus (Desktop Bus) method. A local unprivileged user can exploit this by attempting to register a machine with a specific class value, which may leave behind a usable, attacker-controlled machine object. This allows the attacker to invoke methods on the privileged object, leading to the execution of arbitrary commands with root privileges on the host system.
CVE-2025-14821 2 Libssh, Redhat 5 Libssh, Enterprise Linux, Hardened Images and 2 more 2026-04-29 7.8 High
A flaw was found in libssh. This vulnerability allows local man-in-the-middle attacks, security downgrades of SSH (Secure Shell) connections, and manipulation of trusted host information, posing a significant risk to the confidentiality, integrity, and availability of SSH communications via an insecure default configuration on Windows systems where the library automatically loads configuration files from the C:\etc directory, which can be created and modified by unprivileged local users.
CVE-2025-11731 1 Redhat 3 Enterprise Linux, Hummingbird, Openshift 2026-04-27 3.1 Low
A flaw was found in the exsltFuncResultComp() function of libxslt, which handles EXSLT <func:result> elements during stylesheet parsing. Due to improper type handling, the function may treat an XML document node as a regular XML element node, resulting in a type confusion. This can cause unexpected memory reads and potential crashes. While difficult to exploit, the flaw could lead to application instability or denial of service.
CVE-2025-10911 1 Redhat 3 Enterprise Linux, Hummingbird, Openshift 2026-04-27 5.5 Medium
A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash.
CVE-2025-7424 2 Redhat, Xmlsoft 5 Enterprise Linux, Hummingbird, Openshift and 2 more 2026-04-27 7.5 High
A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior.
CVE-2026-0988 1 Redhat 2 Enterprise Linux, Hummingbird 2026-04-24 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-2026-5704 2 Gnu, Redhat 4 Tar, Enterprise Linux, Hardened Images and 1 more 2026-04-22 5 Medium
A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection.
CVE-2026-1757 1 Redhat 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more 2026-04-22 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-2026-0992 1 Redhat 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more 2026-04-22 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-2026-0990 1 Redhat 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more 2026-04-22 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-2026-0989 1 Redhat 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more 2026-04-22 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-2025-9900 1 Redhat 10 Ai Inference Server, Discovery, Enterprise Linux and 7 more 2026-04-20 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.
CVE-2025-32990 2 Gnu, Redhat 10 Gnutls, Ceph Storage, Discovery and 7 more 2026-04-20 6.5 Medium
A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.
CVE-2025-14104 1 Redhat 6 Ceph Storage, Enterprise Linux, Hummingbird and 3 more 2026-04-20 6.1 Medium
A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte usernames, specifically within the `setpwnam()` function, affecting SUID (Set User ID) login-utils utilities writing to the password database.
CVE-2026-3442 2 Gnu, Redhat 5 Binutils, Enterprise Linux, Hummingbird and 2 more 2026-04-15 6.1 Medium
A flaw was found in GNU Binutils. This vulnerability, a heap-based buffer overflow, specifically an out-of-bounds read, exists in the bfd linker component. An attacker could exploit this by convincing a user to process a specially crafted malicious XCOFF object file. Successful exploitation may lead to the disclosure of sensitive information or cause the application to crash, resulting in an application level denial of service.
CVE-2026-3441 2 Gnu, Redhat 5 Binutils, Enterprise Linux, Hummingbird and 2 more 2026-04-15 6.1 Medium
A flaw was found in GNU Binutils. This heap-based buffer overflow vulnerability, specifically an out-of-bounds read in the bfd linker, allows an attacker to gain access to sensitive information. By convincing a user to process a specially crafted XCOFF object file, an attacker can trigger this flaw, potentially leading to information disclosure or an application level denial of service.
CVE-2026-4647 2 Gnu, Redhat 5 Binutils, Enterprise Linux, Hummingbird and 2 more 2026-04-10 6.1 Medium
A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.
