Out of bounds read in CSS in Google Chrome prior to 146.0.7680.165 allowed a remote attacker to perform out of bounds memory access via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Out of bounds memory read in Google Chrome's CSS parser prior to version 146.0.7680.165 allows remote attackers to access sensitive memory contents through a malicious HTML page. The vulnerability requires user interaction and affects Chrome on multiple platforms including Debian systems, enabling attackers to potentially leak confidential data with high impact on confidentiality and integrity.
Technical ContextAI
The vulnerability resides in Google Chrome's CSS (Cascading Style Sheets) rendering and parsing subsystem, which is responsible for interpreting stylesheet rules and applying visual formatting to web documents. CWE-125 identifies this as a classic out-of-bounds read condition, where the CSS parser attempts to access memory at an index or offset that exceeds the bounds of an allocated buffer or array. This type of flaw typically occurs due to insufficient bounds checking during string parsing, array indexing, or pointer arithmetic in the CSS tokenizer or property value parser. The affected product is Google Chrome across all platforms (Windows, macOS, Linux, and Chrome OS), as indicated by the CPE string cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*, which encompasses all versions prior to the patched release 146.0.7680.165. Attackers exploit this by crafting malicious CSS declarations or selectors that trigger the out-of-bounds condition when parsed, allowing arbitrary memory reads that can disclose heap contents, internal data structures, or other sensitive information.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.165 or later via the built-in auto-update mechanism (Settings > About Chrome), which will automatically download and apply the patch on the next browser restart. For enterprise environments, deploy the patched version via managed software distribution (Windows: Group Policy or SCCM; macOS: Jamf or similar MDM; Linux: package manager updates). Until patching is complete, mitigate risk by restricting user browsing to trusted, curated websites and disabling JavaScript execution for untrusted origins via browser extensions or corporate proxy policies. Additionally, monitor Chrome user populations for successful updates and enforce a compliance deadline for all users within 7 days. The official patch and technical details are available via the Chromium issue tracker at https://issues.chromium.org/issues/488188166 and the Chrome Releases blog at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_23.html.
