The critical thing to understand is namespaces are visibility walls, not security boundaries. They prevent a process from seeing things outside its namespace. They do not prevent a process from exploiting the kernel that implements the namespace. The process still makes syscalls to the same host kernel. If there is a bug in the kernel’s handling of any syscall, the namespace boundary does not help.
Browser font fallback determines the threat. When a page specifies font-family: Arial, Helvetica, sans-serif and a string contains Cyrillic а, the browser checks Arial’s glyph tables, finds Cyrillic coverage, and renders it using Arial’s Cyrillic glyphs — which are pixel-identical to the Latin ones. The CSS font stack you ship determines which column of the danger rate table applies to your users. Arial at 40.8% is a different risk profile from Didot at 19.2%.
