CVE-2026-8093

Description

Memory safety bugs present in Thunderbird 150.0.1. 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 was fixed in Firefox 150.0.2 and Thunderbird 150.0.2.
