Security readout for executives and security teams
This is a serious Chrome browser flaw. A malicious web page could corrupt memory in Chrome's WebAudio component and potentially let an attacker run code in the browser context. Because CISA lists it as known exploited, old Chrome installations should be treated as urgent exposure. Exposure is most likely on endpoints running Google Chrome versions earlier than 78.0.3904.87. Legacy desktop images, unmanaged browsers, and Linux distribution packages that missed vendor updates are the main places to verify. Treat this as a high-priority legacy browser remediation item. The vulnerability is old, but KEV status means unpatched systems represent proven attacker interest and should be removed from the environment quickly. Mitigation focus: Upgrade Google Chrome to 78.0.3904.87 or later.; Confirm managed browser fleets are not pinned to vulnerable Chrome builds.; Apply relevant Linux distribution browser package updates where applicable..
