Report: CVE-2026-40335 - libgphoto2 has OOB read in ptp_unpack_DPV() UINT128/INT128 handling in ptp-pack.c - Guide
CVE ID :CVE-2026-40335 Published : April 18, 2026, 12:16 a.m. | 1 hour, 15 minutes ago Description :libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in `ptp_unpack_DPV()` in `camlibs/ptp2/ptp-pack.c` (lines 622–629). The UINT128 and INT128 cases advance `*offset += 16` without verifying that 16 bytes remain in the buffer. The entry check at line 609 only guarantees `*offset < total` (at least 1 byte available), leaving up to 15 bytes unvalidated. Commit 433bde9888d70aa726e32744cd751d7dbe94379a patches the issue.
