| CVE-2026-42011 | 1 Redhat | 13 Discovery, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-07-20 | 7.4 High |
| A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems. | ||||
| CVE-2026-5260 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-07-20 | 8.2 High |
| A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure. | ||||
| CVE-2026-42015 | 1 Redhat | 13 Discovery, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-07-20 | 5.3 Medium |
| A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts. | ||||
| CVE-2026-42014 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-07-20 | 6.6 Medium |
| A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path. | ||||
| CVE-2026-33846 | 2 Gnu, Redhat | 16 Gnutls, Ai Inference Server, Discovery and 13 more | 2026-07-20 | 7.5 High |
| A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption. | ||||
| CVE-2026-33845 | 2 Gnu, Redhat | 16 Gnutls, Ai Inference Server, Discovery and 13 more | 2026-07-20 | 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-2026-5419 | 2 Gnu, Redhat | 11 Gnutls, Discovery, Enterprise Linux and 8 more | 2026-07-15 | 3.7 Low |
| A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure. | ||||
| CVE-2026-4878 | 2 Libcap Project, Redhat | 18 Libcap, Ai Inference Server, Cost Management and 15 more | 2026-07-15 | 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-2025-14087 | 2 Gnome, Redhat | 15 Glib, Ai Inference Server, Discovery and 12 more | 2026-07-13 | 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-2026-11610 | 1 Redhat | 10 Directory Server, Directory Server E4s, Enterprise Linux and 7 more | 2026-07-08 | 8.8 High |
| A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). After a successful SASL bind with integrity protection (SSF > 0), an authenticated attacker can send a specially crafted oversized LDAP UNBIND packet that is copied into a 512-byte heap receive buffer without a bounds check in sasl_io_recv() in sasl_io.c. This allows up to approximately 2 megabytes of attacker-controlled data to overflow the buffer, causing a denial of service (server crash). In FreeIPA and Red Hat Identity Management deployments, any domain user with a valid Kerberos ticket, any enrolled host, or any service account can trigger this vulnerability over the network after authenticating via GSSAPI. The vulnerable code path has existed since approximately 2013 (389-ds-base 1.3.2) and was not addressed by the CVE-2025-14905 fix, which patched a separate heap overflow in schema.c only. | ||||
| CVE-2026-11774 | 1 Redhat | 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more | 2026-07-08 | 7.6 High |
| An integer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), adding sizeof(uint32_t) to a crafted SASL packet length prefix of 0xFFFFFFFC causes unsigned wraparound to zero, bypassing the nsslapd-maxsasliosize limit and leading to a heap buffer overflow of up to approximately 2 megabytes of attacker-controlled data. After a successful SASL bind with integrity protection (SSF > 0), a remote attacker can cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE). In FreeIPA and Red Hat Identity Management deployments, any domain user with a valid Kerberos ticket, enrolled host, or service account can trigger this vulnerability over the network. This flaw is independent of CVE-2025-14905, which patched schema.c only and did not modify sasl_io.c. | ||||
| CVE-2026-2340 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-07-02 | 6.5 Medium |
| A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file. | ||||
| CVE-2026-4408 | 2 Redhat, Samba | 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more | 2026-07-02 | 9 Critical |
| A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service. | ||||
| CVE-2026-3012 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-07-02 | 8 High |
| A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install it into the local trust store without proper verification. An attacker with the ability to intercept or redirect network traffic could exploit this behavior to supply a malicious certificate authority certificate, potentially allowing interception or spoofing of trusted communications. | ||||
| CVE-2026-1933 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-07-02 | 7.1 High |
| A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types. | ||||
| CVE-2025-6020 | 1 Redhat | 16 Cert Manager, Confidential Compute Attestation, Discovery and 13 more | 2026-06-30 | 7.8 High |
| A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions. | ||||
| CVE-2025-6021 | 2 Redhat, Xmlsoft | 30 Discovery, Enterprise Linux, Enterprise Linux Eus and 27 more | 2026-06-30 | 7.5 High |
| A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input. | ||||
| CVE-2025-5987 | 2 Libssh, Redhat | 6 Libssh, Enterprise Linux, Enterprise Linux Eus and 3 more | 2026-06-30 | 8.1 High |
| A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with the SSH_OK code, resulting in libssh not properly detecting the error returned by the OpenSSL library. This issue can lead to undefined behavior, including compromised data confidentiality and integrity or crashes. | ||||
| CVE-2026-0719 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more | 2026-06-30 | 8.6 High |
| A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk. | ||||
| CVE-2025-61662 | 2 Gnu, Redhat | 10 Grub2, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-06-30 | 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. | ||||
