Use after free in Base in Google Chrome on Linux prior to 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Information disclosure in Google Chrome on Linux prior to 149.0.7827.53 allows a remote attacker who has already compromised the renderer process to read sensitive data from process memory by serving a crafted HTML page that triggers a use-after-free in the Base component. The flaw is rated Medium by Chromium but scored CVSS 8.8 in NVD, and no public exploit identified at time of analysis with an EPSS of 0.03%.
Technical ContextAI
The defect lives in Chrome's Base component, a foundational library shared across the browser providing core primitives (containers, memory utilities, task scheduling) used by the renderer and other processes. CWE-416 (Use After Free) means an object is referenced after its memory has been freed, which on Linux can leak adjacent heap contents - pointers, tokens, or document data - to attacker-controlled code running inside an already-exploited renderer. This bug is therefore a sandbox-adjacent primitive that aids post-exploitation memory inspection rather than an initial code-execution vector, and it specifically affects the Linux build of Chrome (versions prior to 149.0.7827.53).
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.53 for Linux - upgrade immediately by triggering Chrome's built-in updater (chrome://settings/help) or by deploying the new stable package through your Linux distribution or enterprise management channel, then restarting the browser to load the fixed binary. Enterprises should validate the rollout via the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and audit fleet versions to ensure no instance remains below 149.0.7827.53. No workaround is documented; as a temporary compensating control, restrict Linux users to browsing only trusted sites and enforce Chrome's site isolation (already on by default) to limit cross-origin renderer reuse, accepting the trade-off that this does not block the bug itself and only narrows the blast radius if a renderer is already compromised.
