Researcher Claims Root Shell on 2025 Samsung TVs
Original: Root shell on Samsung TV
Why This Matters
Smart TV privacy risks scale to millions of households; root-level exploits amplify that exposure significantly.
Security researcher 'log4j' says they found zero-day vulnerabilities granting root shell access on 2025 Samsung TVs, allegedly exposing always-on microphones, ACR, geo-tracking, and data sharing with 400+ partners.
A researcher going by 'log4j' on X posted on Oct 21, 2026 that after noticing suspiciously targeted ads on their 2025 Samsung TV, they attempted firmware analysis — only to find it AES-encrypted with no accessible keys short of physical UART/JTAG access. So they went another route: zero-days. The result, they claim, is a root shell on current Samsung TVs. A follow-up post detailed what they found inside: always-on microphone functionality, automatic content recognition (ACR), geo-positioning, network mapping, a targeted advertising service, four separate DRM services, and user profile-building telemetry shared with what they describe as 400 partners. No technical write-up has been published yet, though the researcher floated the idea and tagged hardware channel GamersNexus. The post racked up 2.6M views and 29K reposts. A reply from user 'limina' noted the exploit bypasses Samsung Knox with no EL2 hypervisor protections in place — and said they'd now buy Samsung OLED over LG specifically because root access is possible.
