Vulnerability description

DayBreach CVE AI Research

CVE-2026-40333 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

libgphoto2 is a camera access and control library. In versions up to and including 2.5.33, two functions in camlibs/ptp2/ptp-pack.c accept a data pointer but no length parameter, performing unbounded reads. Their callers in ptp_unpack_EOS_events() have xsize available but never pass it, leaving both functions unable to validate reads against the actual buffer boundary. Commit 1817ecead20c2aafa7549dac9619fe38f47b2f53 patches the issue.
