A use-after-free in BigIntPrimitive addition in Hermes prior to commit a6dcafe6ded8e61658b40f5699878cd19a481f80 could have been used by an attacker to leak raw data from Hermes VM’s heap. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected. • https://github.com/facebook/hermes/commit/a6dcafe6ded8e61658b40f5699878cd19a481f80 https://www.facebook.com/security/advisories/cve-2023-24833 • CWE-416: Use After Free •

An integer conversion error in Hermes bytecode generation, prior to commit 6aa825e480d48127b480b08d13adf70033237097, could have been used to perform Out-Of-Bounds operations and subsequently execute arbitrary code. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected. Un error de conversión de enteros en la generación de bytecode de Hermes, anterior al commit 6aa825e480d48127b480b08d13adf70033237097, podría haber sido usado para llevar a cabo operaciones Fuera de Límites y posteriormente ejecutar código arbitrario. Tenga en cuenta que esto sólo es explotable en los casos en que Hermes es usado para ejecutar JavaScript no confiable. • https://github.com/facebook/hermes/commit/6aa825e480d48127b480b08d13adf70033237097 https://www.facebook.com/security/advisories/CVE-2022-40138 • CWE-681: Incorrect Conversion between Numeric Types •
