CVE-2026-7323 is a bundled Mozilla vulnerability covering multiple memory-safety defects affecting Firefox 150.0.0, Firefox ESR 140.10.0, Thunderbird 150.0.0, and Thunderbird ESR 140.10.0. Mozilla indicated that some of the underlying bugs showed evidence of memory corruption and assessed that, with sufficient effort, some could be exploitable for arbitrary code execution. The available information does not identify the specific vulnerable functions or code paths, but the issue class is consistent with memory corruption arising during processing of untrusted content in the affected applications.
