CVE-2026-95293 is an uninitialized-resource vulnerability in the GPU component of Google Chrome before 154.0.8037.57. GLTextureHolder::UploadFromMemory() calls glTexSubImage2D() without checking OpenGL errors and unconditionally reports success. Consequently, failed texture uploads can cause SharedImage backings to be incorrectly marked cleared, allowing readback of potentially uninitialized texture storage. A remote attacker can target this behavior through a crafted HTML page to read memory outside the browser sandbox. Residual-memory disclosure depends on driver initialization behavior; testing demonstrated incorrect initialization tracking and stale-content readback, but not nonzero uninitialized-memory disclosure on the tested drivers.
