CVE-2026-0968 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hummingbird and 1 more 2026-04-18 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 2026-04-18 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 2026-04-18 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 4 Libssh, Enterprise Linux, Hummingbird and 1 more 2026-04-18 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 2026-04-18 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-2025-14512 2 Gnome, Redhat 4 Glib, Enterprise Linux, Hummingbird and 1 more 2026-04-18 6.5 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-2025-14087 2 Gnome, Redhat 3 Glib, Enterprise Linux, Hummingbird 2026-04-18 5.6 Medium
A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings.
CVE-2025-13601 2 Gnome, Redhat 41 Glib, Ceph Storage, Codeready Linux Builder and 38 more 2026-04-18 7.7 High
A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.
CVE-2025-49796 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-04-18 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-2025-9566 1 Redhat 9 Enterprise Linux, Hummingbird, Openshift and 6 more 2026-04-18 8.1 High
There's a vulnerability in podman where an attacker may use the kube play command to overwrite host files when the kube file container a Secrete or a ConfigMap volume mount and such volume contains a symbolic link to a host file path. In a successful attack, the attacker can only control the target file to be overwritten but not the content to be written into the file. Binary-Affected: podman Upstream-version-introduced: v4.0.0 Upstream-version-fixed: v5.6.1
CVE-2026-4878 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-04-18 6.7 Medium
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.
CVE-2026-1757 1 Redhat 4 Enterprise Linux, Hummingbird, Jboss Core Services and 1 more 2026-04-18 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-2026-4775 1 Redhat 2 Enterprise Linux, Hummingbird 2026-04-17 7.8 High
A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution.
CVE-2026-4111 1 Redhat 8 Ai Inference Server, Discovery, Enterprise Linux and 5 more 2026-04-17 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-2025-14831 2 Red Hat, Redhat 13 Enterprise Linux, Ai Inference Server, Ceph Storage and 10 more 2026-04-17 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-2026-5121 2 Libarchive, Redhat 8 Libarchive, Enterprise Linux, Hardened Images and 5 more 2026-04-16 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.
