CVE-2026-40340
Description
A flaw was found in libgphoto2, a library for camera access and control. An out-of-bounds read vulnerability exists in the ptp_unpack_OI() function due to insufficient validation. A local attacker could exploit this by crafting specific input related to the Samsung Galaxy 64-bit objectsize detection heuristic. This could lead to information disclosure or a denial of service by causing the application to crash.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
