About Samsung Exynos 1280 Firmware
CVE-2025-62817 affects Samsung Exynos 1280 Firmware, a product from Samsung. Before acting, confirm where Samsung Exynos 1280 Firmware runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: An issue was discovered in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, 2400, 1580, and 2500. A NULL pointer dereference of session->ncp_hdr_buf in __pilot_parsing_ncp() causes a denial of service.
The weakness class is NULL Pointer Dereference. The program uses an empty pointer and crashes.
Based on its CVSS vector, the flaw can be reached over the network, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.
