CVE‑2026‑11005 describes an out‑of‑bounds (OOB) read vulnerability in the ANGLE graphics library used by Google Chrome on Windows. ANGLE (Almost Native Graphics Layer Engine) translates WebGL and other graphics calls to the underlying native APIs, such as Direct3D. The flaw resides in the buffer‑validation logic when ANGLE processes certain graphics commands, specifically those related to texture sampling or shader execution.
Under normal conditions, ANGLE validates indices and pointers before accessing memory. However, in versions prior to 149.0.7827.53, an attacker who has already compromised the browser’s renderer process can supply a crafted HTML page that triggers a specific sequence of graphics operations. Because the renderer process has been taken over (e.g., via a separate initial vulnerability), the attacker can force ANGLE to read memory that lies beyond the bounds of the intended buffer. This OOB read does not cause a crash or code execution by itself, but it does allow the attacker to leak data from adjacent memory regions.
The leaked data may include sensitive information such as cryptographic keys, authentication tokens, passwords, or other confidential content stored in the renderer’s memory space. Since the renderer process is already compromised, the attacker can combine this OOB read with other techniques to exfiltrate the leaked data or use it to further escalate privileges. The issue is classified as CWE‑125 (Out‑of‑bounds Read) and is rated as Medium severity by the Chromium security team.
Because exploitation requires prior compromise of the renderer process, this vulnerability cannot be exploited on its own from a fully secure browser. However, once an attacker has a foothold in the renderer (e.g., via another memory corruption or logic bug), CVE‑2026‑11005 becomes a powerful information‑disclosure primitive. The attack is delivered via a specially crafted HTML page, making it suitable for drive‑by downloads or phishing campaigns. The vulnerability affects all Windows installations of Google Chrome below version 149.0.7827.53. Upgrading to version 149.0.7827.53 or later applies the necessary bounds‑checking fixes and eliminates the risk.
DailyCVE Form:

What Undercode Say:
Verify Chrome version (Windows)
reg query "HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon" /v version
PowerShell check
(Get-Item "C:\Program Files\Google\Chrome\Application\chrome.exe").VersionInfo.ProductVersion
Compare against fixed version
$fixed = "149.0.7827.53"
$current = (Get-Item "C:\Program Files\Google\Chrome\Application\chrome.exe").VersionInfo.ProductVersion
if ($current -lt $fixed) { Write-Host "VULNERABLE" }
// Malicious HTML snippet to trigger OOB read (conceptual)
const canvas = document.createElement('canvas');
const gl = canvas.getContext('webgl');
const texture = gl.createTexture();
gl.bindTexture(gl.TEXTURE_2D, texture);
gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, 0, 0, 0, gl.RGBA, gl.UNSIGNED_BYTE, null);
// Invalid texture coordinate causing OOB read
gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.LINEAR);
gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_WRAP_S, gl.REPEAT);
gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_WRAP_T, gl.REPEAT);
// Trigger rendering with out-of-range texcoords
Exploit:
- Compromise renderer process using an initial vulnerability (e.g., type confusion, use‑after‑free).
- From within the renderer, load a malicious HTML page that invokes ANGLE with specially crafted WebGL or Direct3D commands.
- ANGLE fails to validate texture indices or shader buffer bounds, causing an out‑of‑bounds read.
- Attacker reads adjacent memory, extracting sensitive data (cookies, tokens, keys, memory layout).
- Leaked data is exfiltrated or used for further exploitation (e.g., sandbox escape).
Protection:
- Update Chrome to version 149.0.7827.53 or later immediately.
- Enable Site Isolation (
chrome://flags/enable-site-per-process) to limit renderer process reuse. - Enforce strict Content Security Policy (CSP) and disable WebGL where not required (
--disable-webgl). - Deploy endpoint detection rules monitoring for abnormal ANGLE crashes or memory access patterns.
- Keep Windows security patches and sandbox mitigations up to date.
Impact:
- Confidentiality breach: Leak of cryptographic secrets, credentials, or PII from renderer memory.
- Escalation of privilege: Information disclosure enables further attacks like sandbox escape or renderer‑to‑browser process pivoting.
- Targeted attacks: Weaponised in drive‑by downloads or phishing campaigns after initial renderer compromise.
- Medium severity but high impact when chained; no code execution on its own.
- Wide attack surface due to ANGLE being present on all Windows Chrome installations below the fixed version.
