| CVE-2026-96674 | 1 Alsa-project | 1 Alsa-lib | 2026-09-23 | 4.4 Medium |
| alsa-lib through 1.2.16.1 computes combined topology element size using 32-bit arithmetic in src/topology/ctl.c, allowing integer overflow that defeats bounds checks. Attackers can supply crafted topology files that wrap size calculations, causing the decoder to read beyond the topology buffer and potentially leak sensitive data or crash the application. | ||||
| CVE-2026-6668 | 1 Pgbouncer | 1 Pgbouncer | 2026-09-23 | 7.5 High |
| Integer overflow in the packet buffer growth logic in PgBouncer through 1.25.2 allows an unauthenticated remote attacker to cause a denial of service. Sufficiently large input makes the buffer size computation overflow, leaving the growth loop unable to terminate. Because PgBouncer serves all clients from a single process, this saturates a CPU core and stalls every pooled connection until the process is killed. Both unauthenticated and authenticated code paths can reach the overflow. | ||||
| CVE-2026-61722 | 1 Fluidsynth | 1 Fluidsynth | 2026-09-23 | 6.8 Medium |
| FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS parser validates articulation chunks using the unsigned expression cbsize + connblocks * 12 without first ensuring that the multiplication and addition fit in 32 bits. A crafted DLS file can supply a large connblocks value that wraps the expression and bypasses the chunk-size check, after which the parser performs approximately one billion 12-byte iterations beyond the chunk boundary. The excessive processing and invalid reads can cause denial of service. Builds with the CMake option enable-native-dls set to OFF do not expose the parser. This issue is fixed in version 2.5.6. | ||||
| CVE-2026-11378 | 1 Ibm | 1 Mq | 2026-09-23 | 8.8 High |
| IBM MQ could allow an authenticated attacker to cause a denial of service or potentially execute arbitrary code due to an integer overflow in distribution list processing. | ||||
| CVE-2026-72986 | 1 Microsoft | 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more | 2026-09-23 | 8.8 High |
| Heap-based buffer overflow in Graphic Fonts allows an unauthorized attacker to execute code over a network. | ||||
| CVE-2026-95619 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-09-23 | 7.7 High |
| A flaw was found in libstdc++. An integer overflow can occur when processing large inputs to the aligned operator new in the C++ library. This vulnerability could lead to an undersized memory allocation, potentially causing memory corruption or application instability. | ||||
| CVE-2026-55191 | 1 Freerdp | 1 Freerdp | 2026-09-22 | 9.8 Critical |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients that negotiate RDPGFX AVC444 with an H.264 decoder backend calculate the intermediate YUV444 allocation size in libfreerdp/codec/h264.c with 32-bit multiplication in avc444_ensure_buffer. A malicious RDP server can supply surface dimensions for which piDstStride multiplied by padDstHeight wraps to a small nonzero value, causing winpr_aligned_recalloc to allocate an undersized buffer before YUV420CombineToYUV444 writes using the actual stride and rectangle dimensions. This can cause a client crash and may permit code execution through attacker-influenced heap corruption. This issue is fixed in version 3.27.0. | ||||
| CVE-2026-18462 | 1 Rti | 1 Connext Professional | 2026-09-22 | N/A |

| CVE-2026-93311 | 1 Freedesktop | 1 Poppler | 2026-09-22 | 4.3 Medium |
| A vulnerability was detected in Freedesktop Poppler 26.07.0. This issue affects the function SampledFunction::SampledFunction of the file poppler/Function.cc of the component SampledFunction. The manipulation of the argument BitsPerSample results in integer overflow. The attack may be performed from remote. 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-2026-84965 | 1 Mongodb | 1 C Driver | 2026-09-22 | 5.1 Medium |
| An integer wraparound in an allocation size calculation in the BSON library's JSON parsing code can cause a buffer to be released while a following copy operation still writes through the stale pointer. On builds where sizes are 32 bits, an unauthenticated party able to supply a sufficiently large JSON input to an application that links the library may cause that application to terminate unexpectedly, resulting in denial of service. | ||||
| CVE-2026-84449 | 1 Struktur | 1 Libheif | 2026-09-22 | 3.7 Low |
| libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.19.6, Op_RGB24_32_to_YCbCr::convert_colorspace() stores image-plane strides in an integer width that can overflow for extremely large RGB images created through heif_image_create() and heif_image_add_plane(). The resulting wrapped stride causes the conversion loop in libheif/color-conversion/rgb2yuv.cc to compute an invalid input pointer and read beyond the allocated interleaved plane while heif_context_encode_image() performs RGB-to-YCbCr conversion. This can crash the encoding process. This issue is fixed in version 1.19.6. | ||||
| CVE-2026-93314 | 1 Freedesktop | 1 Poppler | 2026-09-22 | 6.3 Medium |
| A vulnerability was determined in Freedesktop Poppler 26.07.0. This affects the function FoFiTrueType::mapCodeToGID of the file fofi/FoFiTrueType.cc. Executing a manipulation of the argument segCnt can lead to integer overflow. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. This patch is called ed2a5538cf0a8d3ff908191eda9b73f91a5f952a. It is advisable to implement a patch to correct this issue. | ||||
| CVE-2026-16517 | 2 Libarchive, Redhat | 6 Libarchive, Enterprise Linux, Hardened Images and 3 more | 2026-09-21 | 2.9 Low |
| A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption. | ||||
| CVE-2026-61723 | 1 Fluidsynth | 1 Fluidsynth | 2026-09-21 | 6.8 Medium |
| FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS parser validates ptbl chunks with the unsigned expression cues * 4 + cbsize without checking whether the multiplication and addition fit in 32 bits. A crafted DLS file can supply a large cues value that wraps the expression and passes the chunk-size check, causing poolcues.resize(cues) to request approximately four gigabytes and the parser to read billions of entries beyond the chunk boundary. The excessive allocation and invalid reads can cause denial of service. Builds with enable-native-dls set to OFF are not exposed. This issue is fixed in version 2.5.6. | ||||
| CVE-2026-54571 | 1 Esp32async | 1 Espasyncwebserver | 2026-09-21 | N/A |
| ESPAsyncWebServer is an asynchronous HTTP and WebSocket server library for ESP32, ESP8266, RP2040 and RP2350. Prior to 3.11.1, the multipart/form-data parser in src/WebRequest.cpp stores _boundaryPosition as an 8-bit value while _parseMultipartPostByte processes the boundary. A remote request containing an exactly 256-byte multipart boundary wraps _boundaryPosition from 255 to zero, prevents the boundary parsing loop from terminating, consumes excessive CPU, and triggers a FreeRTOS watchdog reset on affected ESP32 or ESP8266 devices. This issue is fixed in version 3.11.1. | ||||
| CVE-2026-69586 | 1 Microsoft | 21 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 18 more | 2026-09-21 | 9.8 Critical |
| Integer overflow or wraparound in Microsoft Windows PDF allows an unauthorized attacker to execute code over a network. | ||||
| CVE-2026-0194 | 1 Google | 1 Android | 2026-09-21 | 8.4 High |
| In multiple locations, there is a possible permission bypass 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. | ||||
