CVE-2026-53705 Red Hat CVE debrief
CVE-2026-53705 is a high-severity vulnerability in GStreamer's WavPack audio decoder. The flaw occurs when processing specially crafted WavPack files, leading to an integer overflow in buffer size calculation. This causes a small heap allocation, allowing the WavPack library to write decoded audio samples beyond the allocated buffer, resulting in heap memory corruption. The vulnerability affects both 32-bit and 64-bit systems and can be exploited by convincing a user to open a malicious WavPack audio file, potentially leading to application crashes or arbitrary code execution.

Who should care
Users and administrators of applications that utilize GStreamer's WavPack audio decoder, particularly those in multimedia processing or playback software, should be aware of this vulnerability. Developers and maintainers of affected software are advised to apply patches or updates to mitigate the risk.
Technical summary
The vulnerability is caused by an integer overflow in the buffer size calculation (4 * block_samples * channels) in gst_wavpack_dec_handle_frame(). This leads to a small heap allocation, which is then overflowed by the WavPack library writing decoded audio samples. The issue arises from the arithmetic being performed in 32-bit integers before promotion to the allocation size type.
Defensive priority
High
Recommended defensive actions
- Apply patches or updates from the vendor as soon as they become available.
- Be cautious when opening WavPack audio files from untrusted sources.
- Consider using alternative audio decoders or players until a patch is applied.
