DescriptionCVE.org

Use after free in SSL in Google Chrome on ChromeOS prior to 150.0.7871.47 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Use-after-free in Chrome's SSL handling on ChromeOS exposes process memory contents to remote attackers who can serve a crafted HTML page. Only ChromeOS builds of Chrome prior to 150.0.7871.47 are affected - this is not a cross-platform flaw. SSVC rates exploitation status as none and technical impact as partial, and Chromium's own severity classification is Low, making this a routine patch-cycle priority rather than an emergency response item despite the CVSS 6.5 score.

Technical ContextAI

CWE-416 (Use After Free) describes a class of memory-safety bug where code continues to reference a pointer to memory that has already been freed. In this case the defect resides specifically in Chrome's SSL subsystem on ChromeOS, suggesting either a ChromeOS-specific code path or a platform-specific integration of the SSL stack that is absent in other builds. When freed SSL objects are subsequently accessed - for example, during SSL session teardown triggered by page content - stale memory contents can be read, potentially leaking any data co-located with that freed allocation, such as keys, session state, or adjacent heap objects. The ChromeOS-only scope implies the root cause may be in platform-layer SSL handling code rather than the cross-platform BoringSSL core.

RemediationAI

Update Google Chrome on ChromeOS to version 150.0.7871.47 or later, which contains the vendor-released fix for this use-after-free. The patch is distributed through the Chrome stable channel and is documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. ChromeOS devices enrolled in auto-update policies should receive the fix automatically; administrators managing enterprise ChromeOS fleets via Google Admin Console should confirm that minimum version enforcement policies are set to 150.0.7871.47 or higher. No configuration-level workaround neutralizes the SSL-layer defect without patching; however, restricting ChromeOS users to approved URL allowlists via enterprise web filtering would reduce exposure to attacker-hosted pages until the update is applied, at the cost of limiting general browsing access.
