CVE-2026-40333
Description
A flaw was found in libgphoto2, a library used for camera access and control. Two functions within the library's Picture Transfer Protocol (PTP) handling component do not properly validate the size of data being read, allowing for unbounded reads. A local attacker with physical access to a system utilizing libgphoto2 could exploit this vulnerability. This could lead to the disclosure of sensitive information from memory or cause the application to crash, resulting in a denial of service.
Mitigation
To mitigate this vulnerability, restrict physical access to systems running libgphoto2. If camera access and control via libgphoto2 is not required, consider removing the `libgphoto2` package to eliminate the attack surface.
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.
