CVE-2018-6056
Type confusion could lead to a heap out-of-bounds write in V8 in Google Chrome prior to 64.0.3282.168 allowing a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
