What is CVE-2026-53705?

A vulnerability in GStreamer's WavPack audio decoder, found in gst-plugins-good, allows for heap memory corruption due to an integer overflow during buffer size calculation. This flaw occurs when processing specifically crafted WavPack audio files, leading to inadequate heap allocation. As a result, decoded audio samples can be written beyond the allocated memory space, exposing both 32-bit and 64-bit systems to potential crashes or arbitrary code execution. A remote attacker could exploit this vulnerability by persuading users to open malicious WavPack files.
