From 7a2821580c0fd65387c70d432017e31881a90c51 Mon Sep 17 00:00:00 2001 From: Yoshisato Yanagisawa <[email protected]> Date: Tue, 26 Aug 2025 18:06:45 -0700 Subject: [PATCH] Fix race condition in ServiceWorkerVersion::OnTimeoutTimer A race condition between handling request timeouts and starting new requests could lead to memory corruption issues, such as the use-after-free reported in the initial security bug. Specifically, if an error callback for a timed-out request triggers a new fetch request, the timeout info for the new request could be freed while the request is still in flight. This change fixes the race by making the timeout handling logic in OnTimeoutTimer re-entrant. It now iterates through the pending requests, moves the timed-out ones to a separate list, and then iterates over that new list to call the callbacks. This ensures that the main request list is not modified while it's being iterated over. Additionally, this change fixes a DCHECK failure by ensuring that the inflight_requests_ map is updated before calling the error callback in MaybeTimeoutRequest. This prevents a scenario where the callback could trigger another request to finish, leading to an inconsistent state between the request_timeouts_ and inflight_requests_ maps. Bug: 440454442, 40864997 Change-Id: Ie3b4a2c1d0f9e8d7c6b5a4f3e2d1c0b9a8d7e6f5 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6875344 Reviewed-by: Shunya Shishido <[email protected]> Reviewed-by: Keita Suzuki <[email protected]> Commit-Queue: Yoshisato Yanagisawa <[email protected]> Cr-Commit-Position: refs/heads/main@{#1506873} --- diff --git a/content/browser/service_worker/service_worker_version.cc b/content/browser/service_worker/service_worker_version.cc index 6c6c2e57..058d68e 100644 --- a/content/browser/service_worker/service_worker_version.cc +++ b/content/browser/service_worker/service_worker_version.cc @@ -2584,20 +2584,23 @@ return; } - // Are there requests that have not finished before their expiration. - bool has_kill_on_timeout = false; - bool has_continue_on_timeout = false; - // In case, `request_timeouts_` can be modified in the callbacks initiated - // in `MaybeTimeoutRequest`, we keep its contents locally during the - // following while loop. - std::set<InflightRequestTimeoutInfo> request_timeouts; - request_timeouts.swap(request_timeouts_); - auto timeout_iter = request_timeouts.begin(); - while (timeout_iter != request_timeouts.end()) { - const InflightRequestTimeoutInfo& info = *timeout_iter; - if (!RequestExpired(info.expiration_time)) { + // 1.

Use After Free in ServiceWorkerVersion::FinishRequestWithFetchCount() in browser process.
VULNERABILITY DETAILS
Specifically crafted web page can trigger Use After Free of InflightRequestTimeoutInfo object in ServiceWorkerVersion::FinishRequestWithFetchCount(). This bug may potentially be exploited to achieve one click Remote Code Execution in browser process (outside sandbox).
ServiceWorkerVersion connects the actual script with a running service worker. ServiceWorkerVersion Handles requests of different types e.g. install, activate, fetch etc.
These requests usually take some time and need to be processed asynchronously, so its member inflight_requests_ holds in-flight requests:
base::IDMap<std::unique_ptr<InflightRequest>> inflight_requests_;
Since these requests are subjected to expiry, ServiceWorkerVersion also has member request_timeouts_ which is a set of InflightRequestTimeoutInfo to track the timeout information:
std::set<InflightRequestTimeoutInfo> request_timeouts_;
When a request is started, a new InflightRequest object is created in ServiceWorkerVersion::StartRequestWithCustomTimeout() and added to container inflight_requests_. An InflightRequestTimeoutInfo object is also created and added to container request_timeouts_. InflightRequest has one member "timeout_iter" that refers to the corresponding iterator in request_timeouts_.
int ServiceWorkerVersion::StartRequestWithCustomTimeout()
{
...
auto request = std::make_unique<InflightRequest>(std::move(error_callback), clock_->Now(), tick_clock_->NowTicks(),event_type);
InflightRequest* request_rawptr = request.get();
int request_id = inflight_requests_.Add(std::move(request));
...
auto [iter, is_inserted] = request_timeouts_.emplace(
request_id, event_type, expiration_time, timeout_behavior);
...
request_rawptr->timeout_iter = iter;
...
}
When the request is finished, the InflightRequest object is retrieved via request_id. The aforementioned "timeout_iter" member of InflightRequest is used to locate the InflightRequestTimeoutInfo inside request_timeouts_. The corresponding objects in request_timeouts_ and inflight_requests_ are removed respectively.
bool ServiceWorkerVersion::FinishRequestWithFetchCount() {
InflightRequest* request = inflight_requests_.Lookup(request_id);
...
request_timeouts_.erase(request->timeout_iter);
inflight_requests_.Remove(request_id);
...
}
Besides, ServiceWorkerVersion periodically checks "request_timeouts_" for entries that should time out in ServiceWorkerVersion::OnTimeoutTimer() which executes every 30 seconds (kTimeoutTimerDelay = base::Seconds(30)):
void ServiceWorkerVersion::OnTimeoutTimer() {
...
std::set<InflightRequestTimeoutInfo> request_timeouts;
request_timeouts.swap(request_timeouts_);
auto timeout_iter = request_timeouts.begin();
while (timeout_iter != request_timeouts.end()) {
const InflightRequestTimeoutInfo& info = *timeout_iter;
if (!RequestExpired(info.expiration_time)) {
break;
}
if (MaybeTimeoutRequest(info)) {
...
}
}
timeout_iter = request_timeouts.erase(timeout_iter);
}
...
request_timeouts_.swap(request_timeouts);
...
}
If the request is expired, "error_callback" of the request is executed (in MaybeTimeoutRequest()). The InflightRequestTimeoutInfo entry is removed from request_timeouts_ in OnTimeoutTimer(), while the InflightRequest entry is removed from inflight_requests_ in MaybeTimeoutRequest().
bool ServiceWorkerVersion::MaybeTimeoutRequest(
const InflightRequestTimeoutInfo& info) {
InflightRequest* request = inflight_requests_.Lookup(info.id);
...
std::move(request->error_callback)
.Run(blink::ServiceWorkerStatusCode::kErrorTimeout);
inflight_requests_.Remove(info.id);
return true;
}
There is a problem with the swap operation against request_timeouts_ and the MaybeTimeoutRequest() method.
What if a new request object is added to "request_timeouts_" during these operations? Turns out it's possible.
In the window code of the PoC, location.reload() is called after a service worker is registered with scope "/", the fetch request would be intercepted and served by the service worker which has a fetch event listener.
navigator.serviceWorker.register("/svcworker0.js", {scope: "/"});
setTimeout(function(){location.reload()},1000);
In the service worker js code of the PoC, waitUntil() is used to delay the activation process of the service worker for 332000ms ( > 5 minutes).
const p1 = new Promise((resolve, reject) => {
setTimeout(() => {
resolve("foo");
}, 332000);
});
this.onactivate = function (e) {
e.waitUntil(p1);
};
So the activation request would expire (kRequestTimeout = 5 minutes) before the activate handler returns. The timeout value of 332000ms is picked to be > kRequestTimeout + kTimeoutTimerDelay = 5 minutes + 30s = 3300000ms, so ServiceWorkerVersion::OnTimeoutTimer() is definitely called after the activate request expires but before the activate handler returns.
Therefore, the "error_callback" (which is "ServiceWorkerRegistration::OnActivateEventFinished())of the request is executed from aybeTimeoutRequest(). This ultimately leads to the creation of a new InflightRequestTimeoutInfo object for the fetch operation:
ServiceWorkerVersion::MaybeTimeoutRequest()
ServiceWorkerRegistration::OnActivateEventFinished()
ServiceWorkerVersion::SetStatus()
ServiceWorkerControlleeRequestHandler::ContinueWithActivatedVersion()
ServiceWorkerControlleeRequestHandler::CreateLoaderAndStartRequest()
NavigationURLLoaderImpl::MaybeStartLoader()
NavigationURLLoaderImpl::StartInterceptedRequest()
NavigationURLLoaderImpl::CreateThrottlingLoaderAndStart()
ThrottlingURLLoader::CreateLoaderAndStart()
ThrottlingURLLoader::Start()
ThrottlingURLLoader::StartNow()
URLLoaderFactory::CreateLoaderAndStart()
SingleRequestURLLoaderFactory::CreateLoaderAndStart()
SingleRequestURLLoaderFactory::HandlerState::CreateLoaderAndStart()
ServiceWorkerMainResourceLoader::StartRequest()
ServiceWorkerFetchDispatcher::StartWorker()
ServiceWorkerFetchDispatcher::DispatchFetchEvent()
ServiceWorkerVersion::StartRequest(()
ServiceWorkerVersion::StartRequestWithCustomTimeout()
As described above, a new InflightRequest object for the fetch operation is created in ServiceWorkerVersion::StartRequestWithCustomTimeout() and added to container inflight_requests_. An InflightRequestTimeoutInfo object is also created and added to container request_timeouts_.
However, because the swap operation ("request_timeouts.swap(request_timeouts_)") in ServiceWorkerVersion::OnTimeoutTimer(), the new InflightRequestTimeoutInfo object is in member variable request_timeouts_, but is NOT in the local variable request_timeouts. After the timeout checkings and callback executions and the second swap call ("request_timeouts_.swap(request_timeouts)"), the new InflightRequestTimeoutInfo object is in the local variable request_timeouts, but NOT in the member variable request_timeouts_. on the exit of function ServiceWorkerVersion::OnTimeoutTimer(), as the local variable goes out of scope, the new InflightRequestTimeoutInfo object is unexpectedly freed.
At this point, there is inconsistency between request_timeouts_ and inflight_requests_. The new InflightRequest object is still in inflight_requests_, but there is NO corresponding InflightRequestTimeoutInfo object in container request_timeouts_.
When the fetch handler JS code finally returns, ServiceWorkerVersion::FinishRequestWithFetchCount() gets executed. The operations based on the stale "request->timeout_iter" pointer is Use After Free (and/or double free).
I believe this bug probably affects all OSs across all release channels. Crash state on MacOS (UAF_FinishRequestWithFetchCount_crashState_Mac.txt) and ASAN report (UAF_FinishRequestWithFetchCount_ASAN.txt) are also collected and attached here for your reference.
