What is CVE-2022-36938?

The DexLoader function get_stringidx_fromdex() in Redex prior to commit 3b44c64 is susceptible to an out-of-bounds read when it processes the string index table. This vulnerability can be exploited by attackers through specially crafted third-party Android APK files, potentially allowing them to execute arbitrary code remotely. This represents a significant security risk, as it could compromise the integrity of the application and lead to unauthorized access or control.
