Summary

CVE-2026-9122 is a medium-severity Out-of-bounds Read (CWE-125) vulnerability in Google Chrome. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Drive-by Compromise (T1189); ranked at the 19th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-2 (Flaw Remediation) and SC-39 (Process Isolation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires timely application of the vendor patch that eliminates the out-of-bounds read in the Chrome GPU process.

prevent

Architectural memory-protection mechanisms can block or contain the unauthorized read of process memory that underlies CWE-125.

prevent

Process isolation confines the GPU component, limiting the scope of memory that can be read by a crafted web page.

detects

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.

A.8.15 Logging partial match
detects

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

prevents

Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.

prevents

Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.

prevents

Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.

prevents

Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
