libgphoto2-6: libgphoto2 is a camera access and control library
CVE-2026-40340 is fixed in 6 products on 1 platform, first by libgphoto2-6 2.5.27-1ubuntu0.1, released April 17, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
