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-2026-3833 1 Redhat 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more 2026-05-01 6.5 Medium
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-3832 2 Gnu, Redhat 6 Gnutls, Enterprise Linux, Hardened Images and 3 more 2026-05-01 3.7 Low
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
CVE-2026-33845 2 Gnu, Redhat 6 Gnutls, Enterprise Linux, Hardened Images and 3 more 2026-05-01 7.5 High
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
CVE-2026-4878 2 Libcap Project, Redhat 6 Libcap, Enterprise Linux, Hardened Images and 3 more 2026-04-30 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-2026-4424 2 Libarchive, Redhat 18 Libarchive, Enterprise Linux, Enterprise Linux Eus and 15 more 2026-04-30 7.5 High
A flaw was found in libarchive. This heap out-of-bounds read vulnerability exists in the RAR archive processing logic due to improper validation of the LZSS sliding window size after transitions between compression methods. A remote attacker can exploit this by providing a specially crafted RAR archive, leading to the disclosure of sensitive heap memory information without requiring authentication or user interaction.
CVE-2026-4948 2 Firewalld, Redhat 5 Firewalld, Enterprise Linux, Firewalld and 2 more 2026-04-30 5.5 Medium
A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.
CVE-2026-6732 1 Redhat 6 Enterprise Linux, Hummingbird, Jboss Core Services and 3 more 2026-04-30 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-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-2026-0964 2 Libssh, Redhat 6 Libssh, Enterprise Linux, Hardened Images and 3 more 2026-04-30 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-2026-0966 2 Libssh, Redhat 6 Libssh, Enterprise Linux, Hardened Images and 3 more 2026-04-30 8.2 High
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-2025-7425 1 Redhat 17 Cert Manager, Discovery, Enterprise Linux and 14 more 2026-04-30 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-2026-4775 3 Debian, Libtiff, Redhat 5 Debian Linux, Libtiff, Enterprise Linux and 2 more 2026-04-30 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-2025-61662 2 Gnu, Redhat 10 Grub2, Enterprise Linux, Enterprise Linux Eus and 7 more 2026-04-30 7.8 High
A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.
CVE-2026-5121 2 Libarchive, Redhat 14 Libarchive, Enterprise Linux, Hardened Images and 11 more 2026-04-30 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-2026-4111 1 Redhat 11 Ai Inference Server, Discovery, Enterprise Linux and 8 more 2026-04-30 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-2026-5201 2 Gnome, Redhat 9 Gdk-pixbuf, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-04-30 7.5 High
A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.
CVE-2025-4123 2 Grafana, Redhat 6 Grafana, Enterprise Linux, Rhel Aus and 3 more 2026-04-29 7.6 High
A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF. The default Content-Security-Policy (CSP) in Grafana will block the XSS though the `connect-src` directive.
CVE-2026-5265 1 Redhat 2 Enterprise Linux, Fast Datapath 2026-04-29 6.5 Medium
When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length (ip_tot_len for IPv4, ip6_plen for IPv6) without validating it against the actual packet buffer size. A VM can send a short packet with an inflated IP length field that triggers an ICMP error (e.g., by hitting a reject ACL), causing ovn-controller to read heap memory beyond the valid packet data and include it in the ICMP response sent back to the VM.
CVE-2026-34003 2 Redhat, X.org 2 Enterprise Linux, X.org 2026-04-29 7.8 High
A flaw was found in the X.Org X server's XKB key types request validation. A local attacker could send a specially crafted request to the X server, leading to an out-of-bounds memory access vulnerability. This could result in the disclosure of sensitive information or cause the server to crash, leading to a Denial of Service (DoS). In certain configurations, higher impact outcomes may be possible.
