CVE-2026-64834 is an infinite-loop vulnerability in FFmpeg versions 0.6.3 through 8.1.2 affecting RTP/ASF demuxing. The rtp_asf_fix_header function iterates ASF objects without enforcing the 24-byte minimum ASF object-header chunk size. A crafted stream containing a smaller chunk size prevents the loop cursor from advancing, resulting in an infinite loop.
