CVE-2026-126894
Description
A flaw was found in the Skia graphics library in chromium-browser. This out-of-bounds read vulnerability can result in information disclosure. A remote attacker who has compromised the browser renderer process could exploit this flaw by enticing a user to view a crafted HTML page, allowing the attacker to leak sensitive data across different websites.
Statement
This vulnerability is rated as Moderate severity because successful exploitation requires user interaction alongside a pre-existing renderer compromise, limiting the blast radius to unauthorized information leakage. In typical Red Hat Enterprise Linux deployments, exposure is constrained to graphical desktop environments where a user actively browses untrusted web content. The issue does not enable arbitrary system-level code execution or sandbox breakout on the host.
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)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
