CVE-2022-36320 is fixed in 11 products on 2 platforms, first by Mozilla Firefox (en-US) 103.0, released July 26, 2022. It is not reported as exploited. Patch Radar priority: High.
Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 102. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 103.
