CVE-2026-110837

7.1

FreeRDP Heap-based Buffer Overflow Vulnerability

CVSS: 7.1, high high CVSS v3.1
EPSS, next 30 days: 0.3% higher than 20.4% of scored CVEs
Exploitation: No public evidence
Published: 14 Oct 20264 days ago

Description

FreeRDP 2.0.0 before 3.32.0, when built with WITH_LAME=ON and WITH_DSP_FFMPEG=OFF, has a heap-based buffer overflow in freerdp_dsp_decode_mp3 because the right-channel PCM pointer is offset by a byte count treated as short elements. A malicious RDP server can send MP3 audio over rdpsnd so decoded samples cross the heap allocation, crashing the client.
