CVE-2026-48186: Samsung semiconductor improper message handling before AS security activation

CVE-2026-48186 · Severity: info · Published 2026-11-05

Samsung semiconductor products may improperly handle messages received before security initialization is complete. This could allow unexpected behavior or bypass of intended security protections during system startup. The practical impact depends on the specific product and how early-stage message processing is exploited.

Technologies: Samsung Semiconductor Products. Vendors: Samsung.

Technical details

An improper handling vulnerability exists in Samsung semiconductor products' authentication and security (AS) initialization sequence, where messages received prior to security activation are not properly validated or rejected. An attacker with network or adjacent access during the pre-security window could send crafted messages to trigger unexpected behavior. A fix is referenced but specific versions are not provided in the available documentation.
