Description

Electron: Use-after-free in offscreen shared texture release() callback

Impact

Apps that use offscreen rendering with GPU shared textures may be vulnerable to a use-after-free. Under certain conditions, the release() callback provided on a paint event texture can outlive its backing native state, and invoking it after that point dereferences freed memory in the main process, which may lead to a crash or memory corruption.

Apps are only affected if they use offscreen rendering with webPreferences.offscreen: { useSharedTexture: true }. Apps that do not enable shared-texture offscreen rendering are not affected.

Workarounds

Ensure texture.release() is called promptly after the texture has been consumed, before the texture object becomes unreachable.

Fixed Versions

  • 42.0.0-alpha.5
  • 41.1.0
  • 40.8.5
  • 39.8.5
