 - A flaw exists that is is triggered as results of the 'instanceof' operator can be manipulated. With specially crafted web content, a context-dependent attacker can bypass the Xray wrapper mechanism.
 - An unspecified flaw exists that is triggered when drawing and validating elements with the ANGLE graphics library. This may allow a context-dependent attacker to cause a buffer overflow, potentially allowing the execution of arbitrary code.
 - A flaw exists related to speculative execution, which is used as a performance feature to speed up operations. This optimization can result in memory being cached during indirect branch prediction. This may allow a local attacker to train the Branch Target Buffer (BTB) to trigger a false prediction to a specially crafted memory location, causing a speculative execution of a crafted gadget and the caching of arbitrary memory. Using a side-channel attack on the cache the attacker can disclose parts of the privileged kernel memory.
