CVE-2026-125240

EUVD-2026-120190
FFmpeg through 9.0.2 contains a resource leak vulnerability in svt_jpegxs_dec_decode() in libsvtjpegxsdec.c that leaks decoder instances when ff_set_dimensions() rejects frame dimensions. Attackers can supply a crafted JPEG XS stream, for example in MPEG-TS, with oversized headers to repeatedly leak decoder threads and buffers, exhausting memory.
