NXP MQX Classic before 5.0 contains an out-of-bounds write vulnerability in the RTCS UDP recvfrom...

NXP MQX Classic before 5.0 contains an out-of-bounds write vulnerability in the RTCS UDP recvfrom() implementation. Improper enforcement of the application-supplied receive buffer length may allow a crafted UDP packet to overflow the destination buffer, resulting in memory corruption, or denial of service.

CVE-2026-87726 Low · 3.9 CWE-787 Oct 7, 2026

Out-of-bounds Write in NXP NxpNfcRdLib

Insufficient API bounds checking in phalFelica in NXP NXPNfcRdLib RC663 through 07.14.00_Pub may allow an attacker with privileges or an untrusted third party to access unintended memory regions, potentially leading to limited loss of confidentiality, integrity, and availability. All software versions from 07.18.00 onwards have fixed this problem.

CVE-2026-107221 Medium · 6.5 CWE-787 Oct 7, 2026

Excelize: a row whose earlier cell has a higher column reference than its last cell panics index out of range on almost every worksheet read API

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.0.0 to 2.11.0, checkRow sizes its target cell slice from the last cell in XML document order and then re-scatters every cell by its explicit column reference. GetCellValue reaches workSheetReader and checkRow, where targetList is too short for an earlier out-of-order cell. When a crafted row places a higher-column cell before a lower-column final cell and a non-streaming worksheet API reads the sheet, the earlier cell's column index exceeds the slice length derived from the final cell, allowing an attacker to cause an unrecovered panic and terminate the process. No fixed version is available as of this review.

CVE-2026-56851 High · 7.5 CWE-787 Oct 7, 2026

Panic parsing crafted input in x/text/secure/precis in golang.org/x/text

The Nickname profile can panic with an out-of-bounds slice error when transforming crafted input into a short destination buffer.

As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco NX-OS engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-76459 are related to out-of-bounds write issues that are grouped under the Common Weakness Enumeration (CWE) CWE-787.

CVE-2026-46569 High · 7.7 CWE-787 Oct 7, 2026

Out-of-bounds Write in Tuxera Ntfs-3g

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_copy_tail(), in libntfs-3g/index.c, that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by extending a directory, e.g., by creating a file.

CVE-2026-42616 High · 7.8 CWE-787 Oct 7, 2026

Out-of-bounds Write in Tuxera Ntfs-3g

In NTFS-3G before 2026.7.7, a heap buffer overflow exists in cat() in ntfscat.c that allows an attacker to corrupt heap memory in the ntfscat binary by crafting a malicious NTFS image. The overflow is triggered by reading a file.

CVE-2026-103416 Critical · 9.3 CWE-787 Oct 7, 2026

Out-of-bounds Write in Eclipse Foundation Threadx Netx Duo

Out-of-bounds write via the TLS 1.3 handshake message cache in NetX Duo in Eclipse ThreadX NetX Duo 6.5.1.202602 allows a handshake message larger than the cache writes past it and on into the rest of the session control block, which holds pointers. A malicious or compromised server can make a TLS 1.3 client produce such a message before certificate authentication completes, so no server certificate is needed to reach it.

CVE-2026-101258 High · 7.8 CWE-787 Oct 6, 2026

Ghostscript: ghostscript: -dsafer sandbox bypass via type 5 shading oob write and procedure-stream use-after-free

A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process. The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime. An attacker can deliver the document directly or through formats that delegate rendering to Ghostscript (for example EPS import or print conversion workflows). Successful exploitation can compromise confidentiality, integrity, and availability of data accessible to the process running Ghostscript.

CVE-2026-102163 High · 8.8 CWE-787 Oct 6, 2026

Security Advisory 0195

On affected Arista access points with Wireless Intrusion Prevention System (WIPS) active, an unauthenticated attacker within radio frequency (RF) proximity can send a crafted frame to crash the sensor service, disabling WIPS monitoring on the access point, or potentially achieve remote code execution. No wireless association or authentication is required.

CVE-2026-106401 Critical · 9.6 CWE-787 Oct 6, 2026

Out-of-bounds Write in Google Chrome

Out of bounds write in Media in Google Chrome prior to 155.0.8059.39 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)

CVE-2026-106118 High · 7.5 CWE-787 Oct 6, 2026

ImageSharp: Tiled fax TIFF: tile buffer sized by TileWidth but fax decompressor writes scanlines of ImageWidth — heap OOB write

ImageSharp is a 2D graphics library. From 3.0.0 until 4.1.1, tiled TIFF decoding allocates a destination buffer using TileWidth but TiffDecompressorsFactory.Create constructs T4, T6, and Modified Huffman decompressors using the full frame width. TiffDecoderCore.DecodeTilesChunky can therefore direct frame-width fax scanlines into a tile-width buffer when TileWidth is smaller than ImageWidth. The mismatch causes attacker-controlled out-of-bounds writes, heap corruption, and process termination even with legal per-row run codes. This tiled-path vulnerability is distinct from oversized CCITT runs in strip decoding. This issue is fixed in version 4.1.1.

CVE-2026-106117 High · 7.5 CWE-787 Oct 6, 2026

ImageSharp: CCITT fax decompression (T4/Modified Huffman): unbounded WriteBits overflows strip buffer — heap OOB write in SixLabors.ImageSharp

ImageSharp is a 2D graphics library. From 3.0.0 until 4.1.1, decoding a strip TIFF using CCITT Group 3 or Modified Huffman compression can pass attacker-expanded runs to BitWriterUtils.WriteBits without first checking the current row width. T4TiffCompression.WritePixelRun can accumulate oversized makeup-code runs, and ModifiedHuffmanTiffCompression.Decompress validates the width only after writing. The unchecked writes can overflow the strip buffer, corrupt heap memory, and terminate the process. This strip-path vulnerability is distinct from the tiled decompressor-width mismatch. This issue is fixed in version 4.1.1.

CVE-2026-106115 High · 7.5 CWE-787 Oct 6, 2026

ImageSharp: TIFF CCITT T6 encoder writes beyond an undersized output buffer

ImageSharp is a 2D graphics library. From 2.1.0 until 4.1.2, the TIFF CCITT Group 4 encoder allocates Width times rowsPerStrip bytes even though T6BitCompressor.CompressStrip can emit encoded row data and two 12-bit end-of-facsimile-block codes beyond that capacity. TiffCcittCompressor.WriteCode performs unchecked writes, and a decode-and-re-encode flow can inherit TiffCompression.CcittGroup4Fax and one-bit metadata from attacker-supplied input. The resulting out-of-bounds writes can corrupt memory and terminate the process. This issue is fixed in version 4.1.2.

CVE-2026-106113 High · 7.5 CWE-787 Oct 6, 2026

ImageSharp: HistogramEqualization uses an unvalidated luminance as an unchecked histogram index

ImageSharp is a 2D graphics library. From 2.0.0 until 4.1.2, decoding an attacker-supplied 32-bit floating-point TIFF as Image<HalfVector4> and applying HistogramEqualization can produce a non-finite or out-of-range luminance in ColorNumerics.GetBT709Luminance. GrayscaleLevelsRowOperation.Invoke uses the resulting value as an unchecked histogram offset, causing an unsafe out-of-range access and process termination. Adaptive Histogram Equalization and AutoLevel are not affected by this report. This issue is fixed in version 4.1.2.
