Linux Distros Unpatched Vulnerability : CVE-2026-40340

medium Nessus Plugin ID 307459

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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 530563). The function validates `len < PTP_oi_SequenceNumber` (i.e., len < 48) but subsequently accesses offsets 4856, up to 9 bytes beyond the validated boundary, via the Samsung Galaxy 64-bit objectsize detection heuristic. Commit 7c7f515bc88c3d0c4098ac965d313518e0ccbe33 fixes the issue. (CVE-2026-40340)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
