CVE-2026-126880
Description
A flaw was found in the V8 engine in chromium-browser. A remote attacker could exploit this type confusion vulnerability by enticing a user to visit a specially crafted HTML page. Successful exploitation could allow the attacker to execute arbitrary code within the browser's restricted sandbox environment.
Statement
This vulnerability is rated as Important rather than Critical because exploitation is confined to the browser's sandbox environment and requires user interaction to visit an untrusted website. In typical Red Hat Enterprise Linux desktop environments, Chromium is utilized for interactive browsing where exposure depends on navigating to external sites. A remote attacker could exploit this flaw by enticing a user to load maliciously crafted web content, resulting in arbitrary code execution within the constrained renderer process without directly compromising the host operating system.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Understanding the Weakness (CWE)
Other
Technical Impact: Varies by Context
When the product accesses the resource using an incompatible type, this could trigger logical errors because the resource does not have expected properties.
Availability,Integrity,Confidentiality
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart
If a memory buffer is accessed using an incompatible type, and the allocated buffer is smaller than the type that the code is attempting to access, then an attacker could read or write memory outside the bounds of the buffer, leading to a crash or possibly code execution.
