| CVE-2026-5260 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-09-24 | 8.2 High |
| A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure. | ||||
| CVE-2026-96442 | 2 Gnu, Redhat | 2 Emacs, Enterprise Linux | 2026-09-24 | 7.8 High |
| A code execution flaw was found in Emacs, affecting versions prior to 31.2. The Flymake mode using language backends other than Lisp would execute arbitrary code from the edited file while performing syntax checking. Viewing or editing untrusted files using Emacs could lead to arbitrary code execution with the privileges of the user running Emacs. | ||||
| CVE-2026-96269 | 1 Gnu | 1 Emacs | 2026-09-24 | 7.8 High |
| GNU Emacs 28.1 through 31.1 allows arbitrary code execution upon opening a file, because an untrusted value of read-symbol-shorthands affects the intern and unintern functions. This affects the default configuration; no particular user settings are required to trigger it. | ||||
| CVE-2026-18508 | 2 Gnu, Redhat | 8 Tar, Discovery, Enterprise Linux and 5 more | 2026-09-22 | 4.4 Medium |
| A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlinks that escape the intended boundary and, when combined with a preexisting symbolic link under the working directory, may allow writing outside that boundary during a single extraction. | ||||
| CVE-2026-18477 | 2 Gnu, Redhat | 8 Tar, Discovery, Enterprise Linux and 5 more | 2026-09-22 | 4.4 Medium |
| A TOCTOU (Time-of-Check Time-of-Use) vulnerability in GNU tar's incremental dumpdir 'X' rename handling allows a local attacker with write access to a directory being backed up to influence the restore process if the attacker has access to the system where the restore is being performed. During restoration, files or directories may be created, renamed or overwritten outside the intended extraction directory. This could lead to unauthorized file modification or, in some cases, privilege escalation. Exploitation does not require the attacker to modify or craft the archive, and standard backup and restore workflows—including extracting into a newly created directory without using the -P option do not mitigate the issue. | ||||
| CVE-2026-5704 | 2 Gnu, Redhat | 6 Tar, Discovery, Enterprise Linux and 3 more | 2026-09-22 | 5 Medium |
| A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection. | ||||
| CVE-2024-53920 | 2 Gnu, Redhat | 3 Emacs, Enterprise Linux, Rhel Eus | 2026-09-21 | 7.8 High |
| In elisp-mode.el in GNU Emacs before 30.1, a user who chooses to invoke elisp-completion-at-point (for code completion) on untrusted Emacs Lisp source code can trigger unsafe Lisp macro expansion that allows attackers to execute arbitrary code. (This unsafe expansion also occurs if a user chooses to enable on-the-fly diagnosis that byte compiles untrusted Emacs Lisp source code.) | ||||

The exploit is now public and may be used. The project was informed of the problem early through a bug report but has not responded yet. | ||||
| CVE-2026-90801 | 1 Gnu | 1 Binutils | 2026-09-18 | 5.3 Medium |
| A security flaw has been discovered in GNU Binutils 2.47. This impacts the function cache_bwrite of the file bfd/cache.c of the component ld. The manipulation of the argument nbytes results in buffer overflow. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through a bug report but has not responded yet. | ||||
| CVE-2026-90802 | 1 Gnu | 1 Binutils | 2026-09-18 | 4.4 Medium |
| A weakness has been identified in GNU Binutils 2.47. Affected is the function bfd_putl64 of the file bfd/libbfd.c of the component ld. This manipulation causes null pointer dereference. The attack requires local access. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through a bug report but has not responded yet. | ||||
| CVE-2026-90803 | 1 Gnu | 1 Binutils | 2026-09-18 | 5.3 Medium |
| A security vulnerability has been detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_64_relocate_section of the file bfd/elf64-x86-64.c of the component ld. Such manipulation of the argument roff leads to buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. Upgrading to version 2.48 addresses this issue. The name of the patch is 471130b39c03623ec6d78ece377ff4da3f6bfe7b. It is recommended to upgrade the affected component. | ||||
| CVE-2026-91752 | 1 Gnu | 1 Libextractor | 2026-09-17 | 7.5 High |
| GNU libextractor before 1.15 contains a stack-based buffer overflow vulnerability in the process_star_office function that sizes a variable-length stack array from attacker-controlled OLE2 stream data. Attackers can craft malicious StarOffice documents that allocate up to 4 MB on the stack, causing stack overflow and crashing any application extracting metadata from the document. | ||||
| 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. | ||||
| CVE-2026-91782 | 1 Gnu | 1 Binutils | 2026-09-17 | 3.3 Low |
| A vulnerability was detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_allocate_dynrelocs of the file bfd/elfxx-x86.c of the component Dynamic Relocation Allocation. The manipulation results in null pointer dereference. The attack requires a local approach. The exploit is now public and may be used. Upgrading to version 2.48 addresses this issue. The patch is identified as d1268210b6f6/471130b39c0/283d3198bed/0a84e560216/a692a633d40. Upgrading the affected component is recommended. | ||||
