CVE-2026-25087
HighSummary
Podatność typu Use After Free w Apache Arrow C++ występuje w wersjach od 15.0.0 do 23.0.0. Może być wywołana podczas odczytu pliku IPC Arrow z włączonym pre-buforowaniem, jeśli plik IPC zawiera dane z buforami wariadycznymi, co może prowadzić do zapisu w wiszącym wskaźniku.
Risk Assessment
Ryzyko dla organizacji obejmuje losowe awarie aplikacji lub uszkodzenie pamięci podczas odczytu specyficznych plików IPC. Może to prowadzić do nieprzewidywalnych zachowań systemu.
Recommendation
Zaleca się monitorowanie użycia Apache Arrow C++ oraz unikanie włączania pre-buforowania, jeśli to możliwe. Należy również rozważyć aktualizację do najnowszej wersji, aby zminimalizować ryzyko.

Original NVD description (English source)
Use After Free vulnerability in Apache Arrow C++. This issue affects Apache Arrow C++ from 15.0.0 through 23.0.0. It can be triggered when reading an Arrow IPC file (but not an IPC stream) with pre-buffering enabled, if the IPC file contains data with variadic buffers (such as Binary View and String View data). Depending on the number of variadic buffers in a record batch column and on the temporal sequence of multi-threaded IO, a write to a dangling pointer could occur. The value (a `std::shared_ptr<Buffer>` object) that is written to the dangling pointer is not under direct control of the attacker. Pre-buffering is disabled by default but can be enabled using a specific C++ API call (`RecordBatchFileReader::PreBufferMetadata`). The functionality is not exposed in language bindings (Python, Ruby, C GLib), so these bindings are not vulnerable. The most likely consequence of this issue would be random crashes or memory corruption when reading specific kinds of IPC files. If the appli
