### Beta/Release Uplift Approval Request
* **User impact if declined**: Accessing user data (reading local webpage, uploading content) might fail on recent linux kernel + glibc combination (e.g., ubuntu 21.04)
* **Is this code covered by automated tests?**: Yes
* **Has the fix been verified in Nightly?**: Yes
* **Needs manual test from QE?**: No
* **If yes, steps to reproduce**: 
* **List of other uplifts needed**: Bug 1714459
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: Not risky: without the change, feature is broken and usable. The fix is small, consists just in adding handling for the new syscall using existing code path.
* **String changes made/needed**: N/A
