CVE-2026-40340
6.1
CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
Summary
libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read vulnerability in ptp_unpack_OI() in camlibs/ptp2/ptp-pack.c (lines 530–563). The function validates len < PTP_oi_SequenceNumber (i.e., len < 48) but subsequently accesses offsets 48–56, up to 9 bytes beyond the validated boundary, via the Samsung Galaxy 64-bit objectsize detection heuristic. Commit 7c7f515bc88c3d0c4098ac965d313518e0ccbe33 fixes the issue.
