| CVE-2026-42014 | 2 Gnu, Redhat | 15 Gnutls, Discovery, Enterprise Linux and 12 more | 2026-08-25 | 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-2026-42012 | 2 Gnu, Redhat | 15 Gnutls, Discovery, Enterprise Linux and 12 more | 2026-08-25 | 7.1 High |
| A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information. | ||||
| CVE-2026-13757 | 2 P11-kit Project, Redhat | 9 P11-kit, Discovery, Enterprise Linux and 6 more | 2026-08-25 | 6.2 Medium |
| A flaw was found in p11-kit. The RPC message attribute parsing functions p11_rpc_message_get_attribute() and p11_rpc_message_get_attribute_array_value() form a mutually-recursive call chain with no recursion depth limit when processing nested CKA_WRAP_TEMPLATE, CKA_UNWRAP_TEMPLATE, and CKA_DERIVE_TEMPLATE attributes. An unauthenticated attacker with local access to the p11-kit RPC Unix domain socket can send a specially crafted request with deeply nested template attributes, causing stack exhaustion and crashing the p11-kit server process and its dependent services. | ||||
| CVE-2026-2100 | 2 P11-kit Project, Redhat | 8 P11-kit, Cost Management, Enterprise Linux and 5 more | 2026-08-25 | 5.3 Medium |
| A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states. | ||||
| CVE-2026-58016 | 2 Gnome, Redhat | 14 Glib, Discovery, Enterprise Linux and 11 more | 2026-08-25 | 7.5 High |
| A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service. | ||||
| CVE-2026-19685 | 1 Redhat | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-08-24 | 7.1 High |
| NetworkManager did not apply the private_user restriction to the 802-1x.ca-path and phase2-ca-path directory-valued connection properties. This incomplete fix for CVE-2025-9615 allows an unprivileged local user to point a private WPA-Enterprise (802.1X) connection profile's CA path at an attacker-controlled directory, bypassing server certificate validation and enabling credential theft via a rogue access point. | ||||
| CVE-2026-71227 | 2 Redhat, Smuellerdd | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-08-19 | 5.1 Medium |
| A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected application or thread unresponsive. | ||||
| CVE-2026-71226 | 2 Redhat, Smuellerdd | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-08-19 | 7.3 High |
| Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers. | ||||
| CVE-2026-71225 | 2 Redhat, Smuellerdd | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-08-19 | 6.5 Medium |
| A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs (over 64 KiB) in stateful modes such as Counter (CTR) or Cipher Block Chaining (CBC), the library improperly reuses the Initialization Vector (IV) for each internal data chunk. A remote attacker could potentially exploit this by making an application that uses libkcapi process specially crafted large inputs. This can lead to a significant weakening of data confidentiality, as the repeated IV use can expose relationships in encrypted plaintext, and may also affect data integrity by causing incorrect cryptographic processing. | ||||
| CVE-2026-59849 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-08-19 | 3.1 Low |
| A flaw was found in libssh. Logic errors in automatic certificate-based public key authentication can cause libssh clients to loop indefinitely when configured certificates are missing or repeatedly rejected by a server, leading to denial of service. | ||||
| CVE-2026-59842 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-08-19 | 3.7 Low |
| A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthenticated attacker to disclose small amounts of server memory. | ||||
| CVE-2026-15370 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-08-17 | 6.7 Medium |
| A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead to crashes or possible code execution on the server. | ||||
| CVE-2026-59851 | 2 Libssh, Redhat | 4 Libssh, Enterprise Linux, Hardened Images and 1 more | 2026-08-17 | 8.8 High |
| A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users. | ||||
| CVE-2026-19730 | 2 Podman-container-tools, Redhat | 13 Podman, Ansible Automation Platform, Container Native Virtualization and 10 more | 2026-08-14 | 4.2 Medium |
| The 'podman quadlet install --replace' command opens the existing destination file with O_CREATE|O_WRONLY but omits O_TRUNC. When the initial reflink copy attempt fails (common on non-reflink-capable filesystems including many RHEL default XFS configurations), the fallback in ReflinkOrCopy uses io.Copy which performs a non-truncating write. If the original Quadlet is larger than the new Quadlet, the file is not truncated and content from the original is preserved. The command completes with no warning. There is no risk of information leakage as the user already had access to the Quadlet in order to replace it, and in most cases, this would only lead to invalid Quadlet files. However, security-related options from the end of the old Quadlet could be included in the new Quadlet, and if the truncation resulted in a valid Quadlet file, this could result in undesirable behavior. For example, running podman quadlet install --replace to remove a single line from the end of a Quadlet - including security-sensitive content, like AddCapability - will fail, and the option will continue to be used. Further, with Volume Quadlets, this can include additional mounts which can cause content to be unintentionally exposed into containers. If, later, the image is updated then compromised content might be leaked to an attacker. The vulnerable code paths are in pkg/domain/infra/abi/quadlet.go (lines 338-360, O_CREATE|O_WRONLY without O_TRUNC) and vendor/go.podman.io/storage/pkg/fileutils/reflink_linux.go (lines 12-19, non-truncating io.Copy fallback). | ||||
| CVE-2026-19079 | 1 Redhat | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-08-08 | 4.4 Medium |
| A TOCTOU (Time-of-Check-Time-of-Use) race condition vulnerability was found in the fixfiles script in policycoreutils. When running fixfiles relabel or fixfiles restore, the script used find and chcon commands to locate and relabel unlabeled files under /tmp and other directories. A local attacker could exploit a race window between the file discovery and the label change operation by swapping directory components with symlinks, causing chcon to follow the symlink and modify SELinux labels on arbitrary system files. This could undermine SELinux mandatory access control protections on critical files such as /etc/shadow. | ||||
| CVE-2026-18938 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-08-08 | 6.2 Medium |
| A flaw was found in p11-kit. A local attacker, or one with equivalent access to a reachable RPC channel, could exploit an integer overflow vulnerability. By sending specially crafted messages, the attacker can cause the system to miscalculate memory allocation for nested attributes. This leads to a memory corruption issue, specifically a heap out-of-bounds write, which can crash the p11-kit RPC parsing process, resulting in a Denial of Service (DoS). This vulnerability is only exploitable on 32 bit systems. | ||||
| CVE-2026-44605 | 1 Redhat | 3 Enterprise Linux, Hardened Images, Hummingbird | 2026-08-07 | 5.5 Medium |
| A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable. | ||||
| CVE-2026-18839 | 2 Popt-devel, Redhat | 6 Popt-static, Enterprise Linux, Hardened Images and 3 more | 2026-08-07 | 2.2 Low |
| An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of service of the affected application. | ||||
| CVE-2026-12515 | 1 Redhat | 6 Hardened Images, Hummingbird, Satellite and 3 more | 2026-08-04 | 4.3 Medium |
| A flaw was found in Katello's of Red Hat Satellite. A content upload functionality where insufficient authorization checks in the ContentUploadsController allowed users with the edit_products permission to query content information for repositories outside the products they were authorized to manage. An authenticated attacker could exploit this issue to determine whether specific content exists within repositories that should otherwise be inaccessible. This issue does not allow unauthorized modification, import, or publication of content. | ||||
| CVE-2026-9150 | 3 Opensuse, Red Hat, Redhat | 11 Libsolv, Red Hat Satellite 6, Enterprise Linux and 8 more | 2026-07-31 | 6.5 Medium |
| A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system. | ||||
