| CVE-2026-4408 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-09-04 | N/A | 9.0 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-2026-42009 | 2 Gnu, Redhat | 14 Gnutls, Enterprise Linux, Enterprise Linux For Els and 11 more | 2026-09-04 | N/A | 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-2026-33845 | 2 Gnu, Redhat | 3 Gnutls, Enterprise Linux, Openshift Container Platform | 2026-09-04 | N/A | 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-2026-1933 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-09-04 | N/A | 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-2026-48864 | 2 Opensuse, Redhat | 6 Libsolv, Enterprise Linux, Hardened Images and 3 more | 2026-09-03 | N/A | 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-2025-26465 | 4 Debian, Netapp, Openbsd and 1 more | 6 Debian Linux, Active Iq Unified Manager, Ontap and 3 more | 2026-09-02 | N/A | 6.8 MEDIUM |
| A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. | |||||
| CVE-2026-55653 | 2 Openbsd, Redhat | 4 Openssh, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | N/A | 4.3 MEDIUM |
| A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS). | |||||
| CVE-2026-4647 | 2 Gnu, Redhat | 3 Binutils, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.1 MEDIUM |
| A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks. | |||||
| CVE-2026-4426 | 2 Libarchive, Redhat | 4 Libarchive, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | N/A | 6.5 MEDIUM |
| A flaw was found in libarchive. An Undefined Behavior vulnerability exists in the zisofs decompression logic, caused by improper validation of a field (`pz_log2_bs`) read from ISO9660 Rock Ridge extensions. A remote attacker can exploit this by supplying a specially crafted ISO file. This can lead to incorrect memory allocation and potential application crashes, resulting in a denial-of-service (DoS) condition. | |||||
| CVE-2026-3832 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | N/A | 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-2026-3442 | 2 Gnu, Redhat | 3 Binutils, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.1 MEDIUM |

Successful exploitation may lead to the disclosure of sensitive information or cause the application to crash, resulting in an application level denial of service. | |||||
| CVE-2026-3441 | 2 Gnu, Redhat | 3 Binutils, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.1 MEDIUM |
| A flaw was found in GNU Binutils. This heap-based buffer overflow vulnerability, specifically an out-of-bounds read in the bfd linker, allows an attacker to gain access to sensitive information. By convincing a user to process a specially crafted XCOFF object file, an attacker can trigger this flaw, potentially leading to information disclosure or an application level denial of service. | |||||
| CVE-2026-19617 | 1 Redhat | 3 Enterprise Linux, Hardened Images, Openshift Container Platform | 2026-09-01 | N/A | 5.5 MEDIUM |
| A flaw was found in libdm. A local attacker could craft a malicious Logical Volume Manager (LVM) metadata configuration with deeply nested structures. This could lead to uncontrolled recursion in the libdm configuration file parser, exhausting the stack and causing any LVM command reading the metadata to crash. This vulnerability results in a Denial of Service (DoS) for affected systems. | |||||
| CVE-2026-19548 | 1 Redhat | 3 Enterprise Linux, Hardened Images, Openshift Container Platform | 2026-09-01 | N/A | 5.5 MEDIUM |
| Multiple Use-After-Free vulnerabilities were found in the add_archive_element function in ld/ldmain.c of the GNU linker (ld), a component of binutils. The root cause is that plugin_maybe_claim() in ld/plugin.c frees the original BFD object via bfd_close/_bfd_delete_bfd when entry->the_bfd->my_archive == NULL, but the caller retains both the original abfd parameter and a shallow copy (orig_input.the_bfd) as dangling pointers. These dangling pointers are subsequently dereferenced at three distinct locations in add_archive_element: 1. Line ~1442: accessing abfd->my_archive via bfd_usrdata(abfd->my_archive) 2. Line ~1493: multiple accesses to abfd and abfd->my_archive in a conditional check and bfd_get_filename call 3. Line ~1525: dereferencing the shallow copy orig_input.the_bfd->my_archive in trace/verbose logging The vulnerability is triggered when LTO plugins are active (link_info.lto_plugin_active is true) and the input object has abfd->my_archive == NULL, which is a valid state for standalone object files. Red Hat builds binutils with --enable-plugins and --enable-lto, confirming the vulnerable code path is compiled in and reachable. An attacker who can supply a crafted object or archive file to a build process using LTO-enabled linking could exploit this flaw to cause a denial of service (linker crash via segmentation fault). Arbitrary code execution is theoretically possible through heap manipulation but is substantially mitigated by hardening measures including stack protector, FORTIFY_SOURCE, ASLR, and PIE. The attack surface is limited to build-time environments — the linker is a development tool not exposed in production runtime. The most realistic exploitation scenario is a supply chain attack introducing a crafted object file as a build dependency in CI/CD pipelines or development environments. | |||||
| CVE-2026-13757 | 2 P11-kit Project, Redhat | 4 P11-kit, Enterprise Linux, Hardened Images and 1 more | 2026-09-01 | N/A | 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-2026-0992 | 3 Ibm, Redhat, Xmlsoft | 7 Aix, Vios, Enterprise Linux and 4 more | 2026-09-01 | N/A | 2.9 LOW |
| A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition. | |||||
| CVE-2026-0989 | 3 Ibm, Redhat, Xmlsoft | 7 Aix, Vios, Enterprise Linux and 4 more | 2026-09-01 | N/A | 3.7 LOW |
| A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk. | |||||
| CVE-2025-8283 | 1 Redhat | 2 Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 3.7 LOW |
| A vulnerability was found in the netavark package, a network stack for containers used with Podman. Due to dns.podman search domain being removed, netavark may return external servers if a valid A/AAAA record is sent as a response. When creating a container with a given name, this name will be used as the hostname for the container itself, as the podman's search domain is not added anymore the container is using the host's resolv.conf, and the DNS resolver will try to look into the search domains contained on it. If one of the domains contain a name with the same hostname as the running container, the connection will forward to unexpected external servers. | |||||
| CVE-2025-6170 | 2 Redhat, Xmlsoft | 4 Enterprise Linux, Jboss Core Services, Openshift Container Platform and 1 more | 2026-09-01 | N/A | 2.5 LOW |
| A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections. | |||||
| CVE-2025-5918 | 2 Libarchive, Redhat | 3 Libarchive, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 3.9 LOW |
| A vulnerability has been identified in the libarchive library. This flaw can be triggered when file streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-bounds read can lead to unintended consequences, including unpredictable program behavior, memory corruption, or a denial-of-service condition. | |||||
