CVE-2023-30470

CVE-2023-30470 concerns the Hermes JavaScript engine used by React Native. A use-after-free caused by unsound inference in the bytecode generation when optimizations are enabled could allow remote code execution if untrusted JavaScript is executed. The issue is tied to Hermes builds prior to comm...

CVE-2023-28081

CVE-2023-28081 involves a bytecode optimization bug in the Hermes JavaScript engine (used by React Native). The flaw, present in Hermes builds prior to commit e6ed9c1a4b02dc219de1648f44cd808a56171b81, can cause a use-after-free and enable arbitrary code execution via a carefully crafted payload. ...

CVE-2023-24833

CVE-2023-24833 describes a use-after-free in Hermes’ BigIntPrimitive addition. The issue allows an attacker to leak raw data from the Hermes VM heap, but only when untrusted JavaScript is executed by Hermes. Most React Native apps are not affected. The root cause is a use-after-free in the BigInt...
