CVE ID :CVE-2026-40333 Published : April 18, 2026, 12:16 a.m. | 1 hour, 15 minutes ago Description :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.
