| CVE-2026-4424 | 2 Libarchive, Redhat | 7 Libarchive, Enterprise Linux, Enterprise Linux Server Aus and 4 more | 2026-10-14 | N/A | 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-2026-48864 | 2 Opensuse, Redhat | 6 Libsolv, Enterprise Linux, Hardened Images and 3 more | 2026-10-14 | 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-2026-13757 | 2 P11-kit Project, Redhat | 4 P11-kit, Enterprise Linux, Hardened Images and 1 more | 2026-10-14 | 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-2025-14821 | 2 Libssh, Redhat | 2 Libssh, Hardened Images | 2026-10-14 | N/A | 7.8 HIGH |
| A flaw was found in libssh. This vulnerability allows local man-in-the-middle attacks, security downgrades of SSH (Secure Shell) connections, and manipulation of trusted host information, posing a significant risk to the confidentiality, integrity, and availability of SSH communications via an insecure default configuration on Windows systems where the library automatically loads configuration files from the C:\etc directory, which can be created and modified by unprivileged local users. | |||||
| CVE-2026-19548 | 1 Redhat | 3 Enterprise Linux, Hardened Images, Openshift Container Platform | 2026-10-14 | 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-2026-19617 | 1 Redhat | 3 Enterprise Linux, Hardened Images, Openshift Container Platform | 2026-10-02 | 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-2026-55654 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Hardened Images | 2026-09-24 | N/A | 3.7 LOW |
| A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service. | |||||
| CVE-2026-59849 | 2 Libssh, Redhat | 11 Libssh, Enterprise Linux, Enterprise Linux For Els and 8 more | 2026-09-22 | N/A | 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 | 11 Libssh, Enterprise Linux, Enterprise Linux For Els and 8 more | 2026-09-22 | N/A | 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 | 11 Libssh, Enterprise Linux, Enterprise Linux For Els and 8 more | 2026-09-22 | N/A | 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-2026-42055 | 2 F5, Redhat | 11 Dos, Nginx Gateway Fabric, Nginx Ingress Controller and 8 more | 2026-09-14 | N/A | 8.1 HIGH |
| NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_proxy_v2_module and ngx_http_grpc_module modules. This vulnerability exists when the proxy_http_version to 2 or grpc_pass directives are used to proxy HTTP/2 traffic, the ignore_invalid_headers directive is set to off, and the large_client_header_buffers directive size is larger than 2 megabytes. A remote, unauthenticated attacker, along with conditions beyond their control, could send large headers while creating an upstream request. This may cause a heap-based buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | |||||
| CVE-2026-59847 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Hardened Images | 2026-09-04 | N/A | 5.9 MEDIUM |
| A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection. | |||||
| CVE-2026-59850 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Hardened Images | 2026-09-01 | N/A | 4.3 MEDIUM |

| A flaw was found in libssh. A malicious username expanded through %r in ProxyCommand handling can inject shell metacharacters, exposing environment variables and causing unintended shell behavior. | |||||
| CVE-2026-59845 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Hardened Images | 2026-09-01 | N/A | 5.3 MEDIUM |
| A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service. | |||||
| CVE-2026-59844 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Hardened Images | 2026-09-01 | N/A | 6.5 MEDIUM |
| A flaw was found in libssh. A remote authenticated client can issue SSH_FXP_READ requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests. | |||||
| CVE-2026-59843 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Hardened Images | 2026-09-01 | N/A | 6.5 MEDIUM |
| A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSH_MSG_CHANNEL_OPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service. | |||||
| 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-2026-0992 | 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. | |||||
