| CVE-2026-19582 | 2 Gnu, Redhat | 8 Binutils, Enterprise Linux, Hardened Images and 5 more | 2026-08-25 | N/A |
| In binutils 2.46.1 and prior versions, a victim who opens a crafted PE file using binutils could execute arbitrary code unknowningly via a stack buffer overflow out of bounds write. | ||||
| CVE-2026-58043 | 2 Nodejs, Redhat | 3 Node.js, Nodejs, Hummingbird | 2026-08-25 | 8.4 High |
| A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix boundaries. Under `--permission`, an attacker who is granted access to one path can abuse boundary handling to read from or write to paths outside the intended filesystem allowlist. This vulnerability affects Node.js **main**, **22.x**, **24.x**, and **26.x**. | ||||
| CVE-2026-56850 | 2 Nodejs, Redhat | 3 Node.js, Nodejs, Hummingbird | 2026-08-25 | 4.4 Medium |
| A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual TLS (mTLS) client identities to be reused across requests configured with different client certificates. This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**. | ||||
| CVE-2026-19548 | 2 Gnu, Redhat | 7 Binutils, Adminutil, Enterprise Linux and 4 more | 2026-08-25 | 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 | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-08-25 | 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-2026-6473 | 2 Postgresql, Redhat | 2 Postgresql, Hummingbird | 2026-08-25 | 8.8 High |
| Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. | ||||
| CVE-2026-55654 | 3 Openbsd, Openssh, Redhat | 8 Openssh, Openssh, Enterprise Linux and 5 more | 2026-08-25 | 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-2026-5419 | 2 Gnu, Redhat | 11 Gnutls, Discovery, Enterprise Linux and 8 more | 2026-08-25 | 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-2026-3832 | 2 Gnu, Redhat | 9 Gnutls, Discovery, Enterprise Linux and 6 more | 2026-08-25 | 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-2025-6170 | 2 Redhat, Xmlsoft | 9 Discovery, Enterprise Linux, Hummingbird and 6 more | 2026-08-25 | 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-2026-58015 | 2 Gnome, Redhat | 5 Glib, Enterprise Linux, Hardened Images and 2 more | 2026-08-25 | 5.9 Medium |
| A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash. | ||||
| CVE-2026-58014 | 2 Gnome, Redhat | 5 Glib, Enterprise Linux, Hardened Images and 2 more | 2026-08-25 | 7.3 High |
| A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary. | ||||
| CVE-2026-58013 | 2 Gnome, Redhat | 5 Glib, Enterprise Linux, Hardened Images and 2 more | 2026-08-25 | 6.5 Medium |
| A flaw was found in GLib. A buffer over-read can occur in g_io_channel_read_line_backend() in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes or a denial of service when the buffer over-read crosses a page boundary. | ||||
| CVE-2026-58010 | 2 Gnome, Redhat | 5 Glib, Enterprise Linux, Hardened Images and 2 more | 2026-08-25 | 6.5 Medium |
| A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary. | ||||
| CVE-2026-58012 | 2 Gnome, Redhat | 5 Glib, Enterprise Linux, Hardened Images and 2 more | 2026-08-25 | 6.5 Medium |
| A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary. | ||||
| CVE-2026-58011 | 2 Gnome, Redhat | 5 Glib, Enterprise Linux, Hardened Images and 2 more | 2026-08-25 | 6.5 Medium |
| A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service. | ||||
| CVE-2026-55655 | 3 Openbsd, Openssh, Redhat | 8 Openssh, Openssh, Enterprise Linux and 5 more | 2026-08-25 | 5 Medium |
| A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session. | ||||
| CVE-2026-55653 | 3 Openbsd, Openssh, Redhat | 8 Openssh, Openssh, Enterprise Linux and 5 more | 2026-08-25 | 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-2026-48864 | 2 Opensuse, Redhat | 21 Libsolv, Discovery, Enterprise Linux and 18 more | 2026-08-25 | 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-2026-42015 | 1 Redhat | 14 Discovery, Enterprise Linux, Enterprise Linux Eus and 11 more | 2026-08-25 | 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. | ||||
