CVE-2026-92454— JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode
Quick assessment
Affected
Eclipse Foundation Eclipse ThreadX - GUIX
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
GUIX 软件的 JPEG 解码器在读取四种标记段时，未验证每个标记段的长度是否足以容纳其读取的数据。因此，解码器会读取被截断的标记段，从而超出调用方图像缓冲区的末尾。此外，当色度采样因子为零时，会导致块解码循环无法终止。上述两种问题在默认配置下均可复现，该配置中已启用 。

Vulnerability Title
JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode
Source: CVE Program / CVE List V5
Vulnerability Description
The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating. Both reproduce in the default configuration, in which `GX_SOFTWARE_DECODER_SUPPORT` is enabled.
