CVE-2026-5745 1 Redhat 2 Enterprise Linux, Openshift 2026-04-08 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-2025-14821 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hummingbird and 1 more 2026-04-08 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-2025-57854 1 Redhat 1 Openshift Update Service 2026-04-08 6.4 Medium
A container privilege escalation flaw was found in certain OpenShift Update Service (OSUS) images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, may be able to leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.
CVE-2026-35091 2 Corosync, Redhat 4 Corosync, Enterprise Linux, Openshift and 1 more 2026-04-08 8.2 High
A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory contents. This vulnerability affects Corosync when running in totemudp/totemudpu mode, which is the default configuration.
CVE-2026-35092 2 Corosync, Redhat 4 Corosync, Enterprise Linux, Openshift and 1 more 2026-04-08 7.5 High
A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol (UDP) packets. This can cause the service to crash, leading to a denial of service. This vulnerability specifically affects Corosync deployments configured to use totemudp/totemudpu mode.
CVE-2026-4111 1 Redhat 6 Enterprise Linux, Hummingbird, Openshift and 3 more 2026-04-08 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-2025-14104 1 Redhat 6 Ceph Storage, Enterprise Linux, Hummingbird and 3 more 2026-04-08 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-2026-1757 1 Redhat 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more 2026-04-08 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 11 Enterprise Linux, Ceph Storage, Enterprise Linux and 8 more 2026-04-08 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-2026-3184 2 Linux, Redhat 4 Util-linux, Enterprise Linux, Hummingbird and 1 more 2026-04-08 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-2026-3442 2 Gnu, Redhat 5 Binutils, Enterprise Linux, Hummingbird and 2 more 2026-04-08 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 2026-04-08 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-2025-5372 2 Libssh, Redhat 5 Libssh, Enterprise Linux, Openshift and 2 more 2026-04-07 5 Medium
A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the ssh_kdf() function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the function may mistakenly return a success status even when key derivation fails. This results in uninitialized cryptographic key buffers being used in subsequent communication, potentially compromising SSH sessions' confidentiality, integrity, and availability.
CVE-2024-3727 1 Redhat 18 Acm, Advanced Cluster Security, Ansible Automation Platform and 15 more 2026-04-06 8.3 High
