CVE-2026-88372 1 Libsndfile Project 1 Libsndfile 2026-09-27 7.5 High
libsndfile 1.2.2 contains an integer overflow vulnerability in mat4_read_header() when parsing crafted MAT4 (MATLAB v4) files.
CVE-2026-96611 1 Ffmpeg 1 Ffmpeg 2026-09-26 6.9 Medium
FFmpeg before 9.0 has a signed integer overflow in libavformat/mov.c. In mov_read_ispe(), uint32_t width/height values from a crafted HEIF ispe box are stored into signed int fields without bounds checking, allowing values exceeding INT_MAX to become negative. In read_image_grid(), accumulating these values causes signed integer overflow (undefined behavior per C17 section 6.5), which on x86 wraps to a small positive value, bypassing downstream validity checks.
CVE-2026-10758 1 Esri 1 Lerc 2026-09-26 7.5 High
Esri LERC is an open-source image or raster format which supports rapid encoding and decoding for any pixel type. A Heap based Out-of-Bounds Write via Integer Overflow in LERC versions 4.1.0 and earlier may allow a remote, unauthenticated attacker who can pass specifically crafted attacker controlled imagery to an application that uses LERC to crash the application, leading to a denial of service.
CVE-2026-6103 2 Php Group, Redhat 2 Php, Hummingbird 2026-09-26 4.3 Medium
phar_tar_number() parses the octal size field of a TAR header into a uint32_t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlled file content as the next TAR header, which lets a crafted archive inject entries that PharData reports and extracts as if they were genuine.
CVE-2026-100208 1 Microsoft 3 365 Apps, Office 2021, Office 2024 2026-09-26 7.5 High
Integer overflow or wraparound in Microsoft Office Outlook allows an unauthorized attacker to execute code over a network.
CVE-2025-14181 2 Php Group, Redhat 2 Php, Hummingbird 2026-09-26 6.5 Medium
The SOAP HTTP client guards its response buffer growth with a check that relies on signed integer overflow, which is undefined behaviour and is not guaranteed to trigger. When the check is optimised away, a malicious SOAP server can make the client allocate a buffer far smaller than the data it then writes into it, producing a heap buffer overflow.
CVE-2026-88351 1 Ludocode 1 Mpack 2026-09-26 9.8 Critical
An integer overflow vulnerability exists in the MPack Node API in MPack 1.1.1 on 32-bit platforms. When parsing a specially crafted MessagePack array32 or map32 object with an excessively large element count, the page allocation size calculation in mpack_tree_parse_children() can overflow size_t and produce an undersized allocation. Subsequent parsing writes mpack_node_data_t records beyond the allocated heap buffer, resulting in heap-buffer-overflow, memory corruption, and denial of service.
CVE-2026-83601 1 Netdata 1 Netdata 2026-09-26 6.5 Medium
Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized DIMENSION SLOT value that str2ull_encoded passes to pluginsd_rrddim_put_to_slot in src/plugins.d/pluginsd_internals.h without an upper bound. prd_array_create in src/database/rrdset-pluginsd-array.h can then wrap the size_t allocation calculation while retaining the original large array size, causing the subsequent initialization loop to write beyond the undersized heap allocation and crash the parent agent. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.
CVE-2026-62699 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-25 6.8 Medium
Null pointer dereference in Windows Universal Disk Format File System Driver (UDFS) allows an authorized attacker to execute code locally.
CVE-2026-88361 1 Sumatrapdfreader 1 Sumatrapdf 2026-09-25 7.5 High
SumatraPDF 3.6.1 contains an integer overflow vulnerability in EngineMupdf::BuildPageLabelRec() when parsing PDF PageLabels /Nums entries.
CVE-2026-81878 2 Radare, Radareorg 2 Radare2, Radare2 2026-09-25 5.5 Medium
radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's CPython bytecode .pyc marshal parser was vulnerable because the CPython marshal readers accepted a 32-bit string length without rejecting values that overflow the size-plus-one allocation. The vulnerability is triggered by opening or inspecting a crafted .pyc file through r2 or rabin2. A length of 0xffffffff wrapped the allocation to zero before the common byte reader wrote attacker-controlled data and fill bytes beyond the heap allocation. This can cause heap memory corruption and denial of service; arbitrary code execution is possible but has not been demonstrated. This issue is fixed in version 6.2.0.
CVE-2026-15562 1 Redhat 5 Jboss-remoting, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Els and 2 more 2026-09-25 7.5 High
A flaw was found in EAP's jboss-remoting. A remote unauthenticated attacker who can reach :8080 (or :9990, or :4447) and complete an Upgrade: jboss-remoting handshake can cause OOM errors that degrade requests server-wide, leading to denial of service.
CVE-2026-93233 1 Linux 1 Linux Kernel 2026-09-25 N/A
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/dmem: fix callocated underflow on large folio split nouveau_dmem_folio_free() drops chunk->callocated once per freed folio, while a large (compound) device-private folio is only counted once when it is allocated. When such a folio is split, the mm core invokes ->folio_split() (nouveau_dmem_folio_split()) once for each new sub-folio, but the hook only fixes up the sub-folio metadata and leaves chunk->callocated unchanged. Each resulting sub-folio is later freed separately, so after a split the single allocation (+1) is met by N frees (-N), leaving chunk->callocated short by N-1. On the first split/free cycle it underflows: WARN_ON(!chunk->callocated) fires, the unsigned counter wraps and never returns to zero, so the chunk can no longer be reclaimed (nouveau_dmem_fini() also warns on the leaked count). Account for the new sub-folio in the split hook, under the same lock as nouveau_dmem_folio_free(), so the count stays balanced.
CVE-2026-96749 1 Mongodb 1 Python Driver 2026-09-25 8.4 High
An integer overflow in the BSON document encoding component of the MongoDB Python Driver's bundled native extension may occur when a single document is built from an unusually large amount of caller-supplied data. Size arithmetic is performed in a signed 32-bit type, and the guard meant to catch the overflow is written in a form whose behavior is not defined by the C language standard. A party with no privileges who can place a very large value into data that an application encodes may, depending on how the native extension was built, cause a write outside the bounds of an allocated buffer inside the application's own process.
CVE-2026-69408 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-24 9.8 Critical
Integer overflow or wraparound in Microsoft Windows Media Foundation allows an unauthorized attacker to execute code over a network.
CVE-2026-49927 1 Google 1 Android 2026-09-24 7.8 High
In multiple locations, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
CVE-2026-45527 1 Google 1 Android 2026-09-24 4.3 Medium
In convertCleanApertureToRect of HeifCleanAperture.cpp, there is a possible way to cause a temporary denial of service due to an integer overflow. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.
CVE-2026-55648 1 Freerdp 1 Freerdp 2026-09-24 7.5 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, freerdp_image_copy_from_icon_data in libfreerdp/codec/color.c calculates nWidth multiplied by nHeight multiplied by FreeRDPGetBytesPerPixel(format) in 32-bit arithmetic. A malicious RDP server can send a RAIL TS_ICON_INFO update with dimensions such as 32768 by 32768 and 32 bits per pixel so the required-size calculation wraps, bypassing the cbBitsColor source bounds check before freerdp_image_copy_no_overlap reads attacker-controlled icon data. This affects RemoteApp clients using the vulnerable library path, while xfreerdp has a caller-side mitigation. This issue is fixed in version 3.27.0.
CVE-2026-69373 1 Microsoft 25 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 22 more 2026-09-24 6.7 Medium
Integer overflow or wraparound in Windows Overlay Filter allows an authorized attacker to elevate privileges locally.
