Chakra Core vulnerable to privilege escalation due to reading an invalid pointer
ChakraCore and Microsoft Edge in Windows 10 1703, 1709, and Windows Server, version 1709 allows an attacker to gain the same user rights as the current user, due to how the scripting engine handles objects in memory, aka "Scripting Engine Memory Corruption Vulnerability". When trying to get inlineCaches for a ScriptFunctionWithInlineCache, if the function got redefered and was not reparsed, the function body (and inlineCache on function body) won’t be there, potentially leading to a privilege escalation.
