CWE-823
AllowedUse of Out-of-range Pointer Offset
Abstraction: Base · Status: Incomplete
The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.

Title
OpenSlide: Arbitrary memory write with crafted Ventana BIF file
Summary
OpenSlide is a C library for reading whole slide image files. From 3.4.1 until 4.0.1, OpenSlide's parse_level0_xml() processing in src/openslide-vendor-ventana.c accepts nonpositive row or column tile counts from a crafted Ventana BIF file. The invalid counts produce attacker-controlled relative memory offsets and allow arbitrary values to be written at those offsets, affecting all supported platforms and configurations and resulting in a crash or potential arbitrary code execution. This issue is fixed in version 4.0.1.

Title
GPU DDK - rgxfw_to_ptr() does not reject FW private data pointers
Summary
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory.
Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.

Title
NGINX ngx_http_scgi_module and ngx_http_uwsgi_module vulnerability
Summary
A vulnerability exists in the ngx_http_scgi_module and ngx_http_uwsgi_module modules that may result in excessive memory allocation or an over-read of data. When scgi_pass or uwsgi_pass is configured, an unauthenticated attacker with man-in-the-middle (MITM) ability to control responses from an upstream server may be able to read the memory of the NGINX worker process or restart it. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Title
uuid: Missing buffer bounds check in `v3`/`v5`/`v6` when `buf` is provided
Summary
uuid is for the creation of RFC9562 (formerly RFC4122) UUIDs. Prior to 14.0.0, v3, v5, and v6 accept external output buffers but do not reject out-of-range writes (small buf or large offset). This allows silent partial writes into caller-provided buffers. This vulnerability is fixed in 14.0.0.

Title
GPU DDK - Arbitrary write via UFO updates due insufficient pointer validation in rgxfw_to_ptr()
Summary
Kernel software installed and running inside a Guest/Host VM may post improper commands to the GPU Firmware to trigger a write of data outside the intended GPU memory.
A logic error in the address translation allowed a compromised Host (Kernel) to perform arbitrary writes to firmware memory.

Title
lz4_flex: Decompression can leak information from uninitialized memory or reused output buffer
Summary
lz4_flex is a pure Rust implementation of LZ4 compression/decompression. In versions 0.11.5 and below, and 0.12.0, decompressing invalid LZ4 data can leak sensitive information from uninitialized memory or from previous decompression operations. The library fails to properly validate offset values during LZ4 "match copy operations," allowing out-of-bounds reads from the output buffer. The block-based API functions (`decompress_into`, `decompress_into_with_dict`, and others when `safe-decode` is disabled) are affected, while all frame APIs are unaffected. The impact is potential exposure of sensitive data and secrets through crafted or malformed LZ4 input. This issue has been fixed in versions 0.11.6 and 0.12.1.

Title
OOBR in libpcap before 1.10.7
Summary
libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading the OS process memory in the 32GiB around the buffer on 64-bit architectures and in the entire address space on 32-bit architectures.

Title
VB-Audio Voicemeeter & Matrix Drivers DoS via Corrupted IoAllocateMdl Length
Summary
VB-Audio Voicemeeter, Voicemeeter Banana, and Voicemeeter Potato (versions ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 and earlier, respectively), as well as VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a vulnerability in their virtual audio drivers (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys, and vbaudio_vmvaio3*.sys). The drivers allocate non-paged pool and map it into user space, where a length value associated with the allocation is exposed and can be modified by an unprivileged local attacker. On subsequent IOCTL handling, the corrupted length is used directly as the IoAllocateMdl length argument without adequate integrity checks before building and mapping the MDL, which can cause a kernel crash (BSoD), typically PAGE_FAULT_IN_NONPAGED_AREA. This flaw allows a local user to trigger a denial-of-service on affected Windows systems.

Title
GPU DDK - libusc OOB write at TreeRemove during WebGPU shader compilation
Summary
A web page that contains unusual GPU shader code is loaded into the GPU compiler process and can trigger a write out-of-bounds write crash in the GPU shader compiler library. On certain platforms, when the compiler process has system privileges this could enable further exploits on the device.
An edge case using a very small value in GPU shader code can cause a segmentation fault in the GPU shader compiler due to am out-of-bounds write.

CAPEC-129: Pointer Manipulation
This attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.
