TL;DR

electron's bundled WebRTC Pipewire cursor path on Linux contains a race around shared cursor data. Crafted page content that drives WebRTC capture can reach the faulty lifetime handling. Pre-fix builds can hit use-after-free memory corruption in the media stack. The backport serializes access to the Pipewire cursor data to remove the race.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and ship electron desktop apps on Linux.

electron is vulnerable to Use After Free in versions 40.0.0 - 40.10.2 and 41.0.0 - 41.7.1.
