Last modified

CVE-2026-110837 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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.. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
