Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-62814 is a NULL pointer dereference vulnerability (CWE-476) discovered in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, and 2400. The issue occurs in the load_fw_utc_vector() function when dereferencing a NULL ft_handle, resulting in a denial of service. It was published on 2026-03-03 with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity due to its potential for significant availability impact.
The vulnerability can be exploited remotely over the network by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation leads to a denial of service, disrupting system availability without affecting confidentiality or integrity.
