CVE-2026-114045 1 Freerdp 1 Freerdp 2026-10-21 8.8 High
FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsnd_server_select_format() DVI_ADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDC_FORMATS PDUs with an nBlockAlign too small for nChannels, causing an unbounded heap write during server audio playback, potentially enabling code execution.

CVE-2026-84268 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-10-21 8.8 High
A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution.
CVE-2026-97763 1 Microsoft 12 365 Apps, Microsoft 365, Microsoft Office Ltsc 2021 and 9 more 2026-10-20 8.8 High
Heap-based buffer overflow in Microsoft Office Excel allows an unauthorized attacker to execute code over a network.
CVE-2026-92539 1 Grafana 1 Grafana Enterprise 2026-10-20 6.7 Medium
A service account with user-management permissions in one organization can read, modify, disable or delete users belonging to other organizations on the same Grafana instance through the SCIM API (insecure direct object reference). Only Grafana Enterprise instances with SCIM enabled are affected.
CVE-2025-71436 1 Librdf 1 Raptor Rdf Syntax Library 2026-10-20 7.1 High
Raptor RDF Syntax Library from 2.0.15 through 2.0.16 contains a heap-based buffer overflow vulnerability in raptor_new_term_from_counted_literal() caused by truncating language tag length to an unsigned char. Attackers can supply Turtle, TriG, N-Triples or N-Quads documents with language tags of 256 bytes or longer to corrupt heap memory, crash applications, and possibly execute code.
CVE-2025-60480 1 Gpac 1 Mp4box 2026-10-20 5.5 Medium
A heap buffer overflow in the gf_odf_ac4_cfg_alternative_info function (/odf/descriptors.c) of GPAC Project/MP4Box 2.5-DEV-rev1593-gfe88c3545-master allows attackers to cause a Denial of Service (DoS) via supplying a crafted AC4 file.
CVE-2026-97773 1 Microsoft 14 365 Apps, Microsoft 365, Microsoft 365 Apps For Enterprise and 11 more 2026-10-20 8.8 High
Heap-based buffer overflow in Microsoft Office Excel allows an unauthorized attacker to execute code over a network.
CVE-2026-102209 1 Microsoft 2 Windows 11 26h1, Windows 11 26h1 2026-10-20 7 High

CVE-2026-86830 1 Aws 1 Iam-identity-center-team 2026-10-20 7.2 High
Incorrect privilege assignment in Temporary Elevated Access Management (TEAM) for AWS IAM Identity Center solution before version 1.5.1 might allow an authenticated remote user with application-level access to read, approve, modify, or revoke arbitrary access requests, thereby obtaining unintended temporary elevated access to the AWS accounts accessed using the TEAM deployment. This issue has been addressed in TEAM version 1.5.1 or later. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
CVE-2026-102189 1 Microsoft 13 Windows 11 23h2, Windows 11 23h2, Windows 11 24h2 and 10 more 2026-10-20 7 High
Heap-based buffer overflow in Windows Storage allows an authorized attacker to elevate privileges locally.
CVE-2026-58379 2 Gimp, Redhat 6 Gimp, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-10-20 7.3 High
A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory.
CVE-2026-100203 1 Microsoft 23 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 20 more 2026-10-20 7 High
