FFmpeg through 9.0.2 contains a reachable assertion vulnerability in the TTA encoder's tta_encode_frame() in libavcodec/ttaenc.c, which never reserves output packet space for the 4-byte CRC. Attackers can supply audio whose sample values and length produce a small, poorly compressible final frame, triggering the av_assert0() in flush_put_bits() and aborting applications transcoding to TTA.

CVE-2026-1209805.3 MÉD—
——0On affected platforms running Arista EOS with VPLS-BGP enabled, an attacker who has established a BGP session with the PE routers can send a specially crafted BGP packet to cause the BGP agent to restart unexpectedly.5hCVE-2026-1252464.7 MÉD4.8%
——1FFmpeg through 9.0.2 contains a denial of service vulnerability in cbs_jpeg_assemble_fragment() that miscounts 0xff stuffing bytes in JPEG scan headers. Attackers can supply a crafted JPEG/MJPEG stream with 0xff in the scan header, triggering an av_assert0 abort when CBS-based bitstream filters process it.1dCVE-2026-1252385.5 MÉD5.8%
——2FFmpeg through 9.0.2 contains a reachable assertion vulnerability in libxevd_receive_frame() in libavcodec/libxevd.c that returns success when an access unit produces no frame. Attackers can supply a crafted EVC file with truncated or picture-less access units to trigger the av_assert0() on frame->private_ref, aborting any decoding application.1dCVE-2026-1252374.7 MÉD4.8%
——1FFmpeg 8.1 through 9.0.2 contains a denial of service vulnerability in libavcodec/dpx.c that leaves dpx->hwaccel_picture_private allocated when Vulkan hwaccel callbacks fail. Attackers can supply crafted DPX images that make start_frame, decode_slice or end_frame fail, triggering an av_assert0 abort on the next frame and terminating the decoding application.1dCVE-2026-1251894.7 MÉD4.7%
——1FFmpeg 8.1 through 9.0.2 contains a denial of service vulnerability in the lcevc_metadata bitstream filter caused by a process block position mismatch in lcevc_metadata_handle_vui(). Attackers can supply crafted LCEVC access units with two IDR or non-IDR NAL units to trigger an av_assert0 failure in ff_cbs_lcevc_list_add(), aborting the application.1dCVE-2026-174276.5 MÉD8.8%
——3IBM Power Systems Firmware FW1060.00 through FW1060.81, OP940.00 through OP940.A2, OP910.00 through OP910.95, and OP940.00 through OP940.82 could allow a remote attacker to cause a denial of service due to improper validation of input length.1d
