CVE-2026-53705: Integer Overflow or Wraparound in Red Hat Red Hat Enterprise Linux 10
A flaw was found in GStreamer's WavPack audio decoder in gst-plugins-good. When processing a specially crafted WavPack file, an integer overflow in the buffer size calculation (4 * block_samples * channels) in gst_wavpack_dec_handle_frame() causes a very small heap allocation. The WavPack library then writes decoded audio samples far beyond the allocated buffer, resulting in heap memory corruption. This affects both 32-bit and 64-bit systems since the arithmetic is performed in 32-bit integers before promotion to the allocation size type. A remote attacker could use this flaw to crash an application or potentially execute arbitrary code by convincing a user to open a malicious WavPack audio file.
AI Analysis
Technical Summary
CVE-2026-53705 is an integer overflow vulnerability in the gst_wavpack_dec_handle_frame() function of GStreamer's WavPack audio decoder within gst-plugins-good on Red Hat Enterprise Linux 10. The vulnerability arises from a 32-bit integer overflow in the calculation of buffer size (4 * block_samples * channels), resulting in an insufficient heap allocation. Subsequently, the WavPack library writes decoded audio samples beyond the allocated buffer, causing heap memory corruption. Both 32-bit and 64-bit systems are affected due to the arithmetic being performed in 32-bit integers before promotion. A remote attacker could exploit this by convincing a user to open a crafted WavPack file, potentially leading to application crashes or arbitrary code execution.
Potential Impact
Successful exploitation can lead to heap memory corruption, causing application crashes (denial of service) or potentially arbitrary code execution with the privileges of the affected application user. The vulnerability requires user interaction (opening a malicious file) and is remotely exploitable via crafted media content.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://access.redhat.com/security/cve/CVE-2026-53705 for current remediation guidance. Until a patch is available, avoid opening untrusted WavPack audio files to mitigate risk.
