CVE-2026-24677
Fixed in a distro release EPSS <1%CVSS 8.7
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, ecam_encoder_compress_h264 trusts server-controlled dimensions and does not validate the source buffer size, leading to an out-of-bounds read in sws_scale. This vulnerability is fixed in 3.22.0.
