| CVE-2026-59842 | 2 Libssh, Redhat | 12 Libssh, Enterprise Linux, Enterprise Linux For Els and 9 more | 2026-09-22 | 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 | 12 Libssh, Enterprise Linux, Enterprise Linux For Els and 9 more | 2026-09-22 | 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-2026-19730 | 2 Podman-container-tools, Redhat | 13 Podman, Ansible Automation Platform, Container Native Virtualization and 10 more | 2026-09-22 | 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-2026-16517 | 2 Libarchive, Redhat | 6 Libarchive, Enterprise Linux, Hardened Images and 3 more | 2026-09-21 | 2.9 Low |
| A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption. | ||||
| CVE-2026-76781 | 1 Redhat | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-09-21 | 5.5 Medium |
| A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a `nextCatalog` element lacks its mandatory `catalog` attribute, leading to the application crashing and causing a Denial of Service (DoS). | ||||
| CVE-2026-93653 | 2 Poppler, Redhat | 4 Poppler, Enterprise Linux, Hardened Images and 1 more | 2026-09-21 | 5.5 Medium |
| A denial of service flaw was found in Poppler's Splash backend. A crafted PDF with tiling-pattern geometry approaching the int32 boundary can cause SplashOutputDev::tilingPatternFill to compute an attacker-controlled repeat count that drives an excessively long loop in the pattern-fill scanline routine, without a corresponding memory allocation. An attacker could exploit this by supplying a malicious PDF to an application that renders it via Poppler's Splash backend, causing the rendering process to consume 100% CPU for an attacker-controlled, extended duration. | ||||
| CVE-2026-71227 | 2 Redhat, Smuellerdd | 7 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 4 more | 2026-09-21 | 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 | 7 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 4 more | 2026-09-21 | 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 | 7 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 4 more | 2026-09-21 | 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-2026-12912 | 2 Libtiff, Redhat | 11 Libtiff, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-09-21 | 7.3 High |
| A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS). | ||||
| CVE-2026-87876 | 2 Openprinting, Redhat | 6 Cups, Enterprise Linux, Hardened Images and 3 more | 2026-09-21 | 3 Low |
| Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations. | ||||
| CVE-2026-42784 | 3 Red Hat, Redhat, Sequoia-pgp | 12 Enterprise Linux, Ansible Automation Platform, Confidential Compute Attestation and 9 more | 2026-09-21 | 7.4 High |
| A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity. | ||||
| CVE-2026-15816 | 1 Redhat | 12 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 9 more | 2026-09-21 | 7.5 High |
| A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling. | ||||
| CVE-2026-6893 | 1 Redhat | 13 Dracut, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-09-21 | 7.5 High |
| A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior. | ||||
| CVE-2026-48864 | 2 Opensuse, Redhat | 21 Libsolv, Discovery, Enterprise Linux and 18 more | 2026-09-17 | 7.8 High |
| A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service. | ||||
| CVE-2026-3833 | 2 Gnu, Redhat | 15 Gnutls, Discovery, Enterprise Linux and 12 more | 2026-09-17 | 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-2026-42010 | 2 Gnu, Redhat | 15 Gnutls, Ai Inference Server, Discovery and 12 more | 2026-09-17 | 7.1 High |
| A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process. | ||||
| CVE-2026-42009 | 2 Gnu, Redhat | 26 Gnutls, Ai Inference Server, Discovery and 23 more | 2026-09-17 | 7.5 High |
| A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service. | ||||
| CVE-2026-33846 | 2 Gnu, Redhat | 16 Gnutls, Ai Inference Server, Discovery and 13 more | 2026-09-17 | 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 | 2026-09-17 | 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. | ||||
