CVE-2023-24832 WRITEUP HIGH WRITEUP
Hermes <5cae9f72975cf0e5a62b27fdd8b01f103e198708 - Memory Corruption
A null pointer dereference bug in Hermes prior to commit 5cae9f72975cf0e5a62b27fdd8b01f103e198708 could have been used by an attacker to crash an Hermes runtime where the EnableHermesInternal config option was set to true. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.
CVSS 7.5
CVE-2023-30470 WRITEUP CRITICAL WRITEUP
Hermes - Use-After-Free via Bytecode Generation Optimization
A use-after-free related to unsound inference in the bytecode generation when optimizations are enabled for Hermes prior to commit da8990f737ebb9d9810633502f65ed462b819c09 could have been used by an attacker to achieve remote code execution. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.
