CVE-2026-92454JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode
Medium 6.1
In plain English
A medium-severity out-of-bounds read in Eclipse ThreadX - GUIX from Eclipse Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 4% of all known vulnerabilities).
Official 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.
