CVE-2026-15769
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsufficient validation of untrusted input in Linux Toolkit Theming in Google Chrome on Linux prior to 150.0.7871.125 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA sandbox escape vulnerability exists in Chrome's Linux Toolkit Theming component due to insufficient validation of untrusted input. An attacker who has already compromised the renderer process can exploit this via a crafted HTML page to escape Chrome's sandbox isolation.
