**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 116 Firefox ESR versions prior to 102.14 Firefox ESR versions prior to 115.1 **Description** The issue is related to incorrect cleanup or release of resources in the WASM JIT component of Firefox browsers. This could allow a remote attacker to cause a denial of service. In some cases, a stale value could be used for a global variable in WASM JIT analysis, resulting in incorrect compilation and a potentially exploitable crash in the content process. **Recommendations** For Firefox versions prior to 116, update to version 116 or later. For Firefox ESR versions prior to 102.14, update to version 102.14 or later. For Firefox ESR versions prior to 115.1, update to version 115.1 or later.
