About this tag
The css side channel tag covers Chrome security reports about browser rendering leaks affecting Windows and other desktop platforms. The tagged discussions focus on CVE-2026-14085 and CVE-2026-14012, two Chromium issues disclosed on June 30, 2026 and addressed in Chrome 150.0.7871.47. They describe how crafted HTML pages could use CSS-related rendering or physical side-channel signals to expose cross-origin data or potentially sensitive process-memory information. Coverage also explains the differing severity ratings, including low and medium classifications, and why these issues still matter for browser privacy boundaries. For Windows users, the practical theme is keeping Chrome updated rather than treating CSS as only a presentation feature.
