fix: main process crashes from WebUI host matching, worker AI bindings, extension background page media and serial port revocation - #53333
Merged
Conversation
…s, extension background page media and serial port revocation (#53305) - Only treat chrome://accessibility and devtools://devtools (or chrome://) as WebUI URLs; matching on host alone made an ordinary navigation to http://accessibility/ create WebUI bindings for a non-WebUI process. - Don't route LanguageModel requests that have no live document (workers) to the local AI handler; report them as unavailable instead of dereferencing a null frame. - Create the WebContentsPermissionHelper for every WebContents that api::WebContents becomes the delegate of, including extension background pages, so media/pointer-lock permission checks have a helper to use. - Return early from SerialChooserContext::RevokePortPermissionWebInitiated when the port is no longer known instead of dereferencing end().

##### [v44.2.0](https://github.com/electron/electron/releases/tag/v44.2.0) ### Release Notes for v44.2.0 #### Fixes - Fixed a pending read on a `net.request` chunked upload stream inside a protocol handler never settling when the request failed or was aborted. [#53373](electron/electron#53373) <sup>(Also in [43](electron/electron#53374), [45](https://github.com/electron/electron/pull/53368))</sup> - Fixed a potential crash when using `menu.popup` with a frame from an offscreen rendered window. [#53362](electron/electron#53362) <sup>(Also in [43](https://github.com/electron/electron/pull/53432))</sup> - Fixed an intermittent crash (access violation) on Windows when an ASAR integrity violation is detected, so the process now exits with code 1 as intended. [#53455](electron/electron#53455) <sup>(Also in [43](electron/electron#53456), [45](https://github.com/electron/electron/pull/53438))</sup> - Fixed application crash after a large number of IPC messages from renderers. [#53417](electron/electron#53417) <sup>(Also in [42](electron/electron#53419), [43](electron/electron#53420), [45](https://github.com/electron/electron/pull/53418))</sup> - Fixed native addons deriving from `node::ObjectWrap` aborting during garbage collection on Node.js 24.19.0 and later. [#53392](electron/electron#53392) <sup>(Also in [42](electron/electron#53394), [43](electron/electron#53393), [45](https://github.com/electron/electron/pull/53391))</sup> #### Other Changes - Backported fixes from upstream ANGLE, Chromium, Skia and V8. [#53479](electron/electron#53479) - Improved throughput of responses that `protocol.handle` handlers return straight from `net.fetch`. [#53378](electron/electron#53378) - Updated Chromium to 152.0.7977.76. [#53382](electron/electron#53382) - Updated Node.js to v24.20.0. [#53250](electron/electron#53250) ##### [v44.1.1](https://github.com/electron/electron/releases/tag/v44.1.1) ### Release Notes for v44.1.1 #### Fixes - Fixed `chrome.tabs.query()` returning tab `url` and `title` to extensions without the `tabs` permission or host access, aligning with `tabs.get`. [#53354](electron/electron#53354) <sup>(Also in [42](electron/electron#53355), [43](electron/electron#53356), [45](https://github.com/electron/electron/pull/53353))</sup> - Fixed a renderer crash when an array with a throwing property getter is passed across `contextBridge`, and several main/utility-process crashes when option objects passed to Electron APIs contain throwing accessors or Proxy traps. [#53331](electron/electron#53331) <sup>(Also in [42](electron/electron#53329), [43](https://github.com/electron/electron/pull/53330))</sup> - Fixed an intermittent crash at startup on Linux caused by a race between Pango and the main thread initializing fontconfig. [#53340](electron/electron#53340) <sup>(Also in [43](electron/electron#53339), [45](https://github.com/electron/electron/pull/53338))</sup> - Fixed an issue where an exception thrown by a property getter on an object passed through `contextBridge` was swallowed instead of being thrown back to the caller. [#53335](electron/electron#53335) <sup>(Also in [43](electron/electron#53334), [45](https://github.com/electron/electron/pull/53297))</sup> - Fixed main process crashes when navigating to `http://accessibility/` or `http://devtools/`, when an extension background page used `navigator.mediaDevices`, and when calling `SerialPort.forget()` for a disconnected device. [#53333](electron/electron#53333) <sup>(Also in [43](electron/electron#53332), [45](https://github.com/electron/electron/pull/53325))</sup> - Fixed the PDF viewer failing to save an edited PDF with `NotAllowedError: Third party iframes are not allowed to show a file picker`.

Backport of #53305
See that PR for details. The
LanguageModelworker fix is left out: the local AI handler does not exist on this line.Notes: Fixed main process crashes when navigating to
http://accessibility/orhttp://devtools/, when an extension background page usednavigator.mediaDevices, and when callingSerialPort.forget()for a disconnected device.
