Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-62817, published on 2026-03-03, is a NULL pointer dereference vulnerability (CWE-476) discovered in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, 2400, 1580, and 2500. The flaw occurs in the __pilot_parsing_ncp() function due to dereferencing session->ncp_hdr_buf when it is NULL, leading to a denial of service condition.
The vulnerability carries 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 it is exploitable over the network with low attack complexity, requiring no privileges or user interaction. Unauthenticated remote attackers can trigger the issue, achieving high-impact denial of service on affected Exynos processors without compromising confidentiality or integrity.
