CVE-2026-40339

libgphoto2 is a camera access and control library.

Published Apr 18, 2026 · updated Jun 17, 2026

libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in in (line 842). The function reads the FormFlag byte via without a prior bounds check. The standard at lines 686–687 correctly validates before this same read, but the Sony variant omits this check entirely. Commit 09f8a940b1e418b5693f5c11e3016a1ad2cea62d fixes the issue.
