CVE-2026-92454
JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode
CVSS Score

EPSS Percentile
0th
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.
