CVE-2026-19138
Description
A flaw was found in Google Chrome's CrashReporting component. A heap buffer overflow vulnerability allows a remote attacker, who has already compromised the renderer process, to potentially escape the browser's security sandbox by crafting a malicious HTML page. This could lead to further compromise of the user's system.
Statement
This Important vulnerability in Chromium's CrashReporting component allows a remote attacker to perform a sandbox escape. After an initial compromise of the renderer process, typically through user interaction with a crafted HTML page, a heap buffer overflow can be exploited to bypass the browser's security sandbox. This is considered Important due to the potential for further system compromise once the sandbox is breached, despite the prerequisite of an already compromised renderer.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
