CVE-2026-48183 · Severity: info · Published 2026-11-05

Samsung semiconductor memory components (DRAM, eStorage, MCP) have an improper permission handling vulnerability in buffer operations that allows untrusted applications to create memory mappings with elevated privileges. An attacker could bypass security restrictions and gain unauthorized access to sensitive data or system resources on devices using affected Samsung memory.

Technologies: [Samsung Exynos](https://junglewise.ai/threats/technologies/exynos). Vendors: [Samsung](https://junglewise.ai/threats/vendors/samsung).

## Technical details

Improper permission handling during buffer operations allows untrusted applications to create memory mappings with inappropriate permissions, potentially leading to privilege escalation. The vulnerability affects Samsung semiconductor memory components and requires local access but no authentication. This could allow arbitrary code execution or unauthorized access to protected memory regions.
