Out of bounds read in Codecs in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to obtain potentially sensitive information from process memory via a malicious file. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds read in Chrome's codec implementation allows remote attackers to extract potentially sensitive data from process memory by delivering a malicious media file. Affects Chrome versions prior to 148.0.7778.96. The vulnerability requires user interaction (opening or playing a crafted file) but operates over the network. Google rated this as Medium severity within the Chromium security framework.
Technical ContextAI
The vulnerability exists in the codecs module of Google Chrome, a widely-deployed web browser that processes multimedia content. Codecs are software libraries that encode and decode audio and video streams. A classic out-of-bounds read (CWE-125) occurs when the codec parser attempts to access memory beyond allocated buffer boundaries while processing malformed media frames. This does not cause memory corruption or code execution but exposes adjacent memory contents to the attacker. The vulnerability affects all Chrome versions before the fixed version 148.0.7778.96 across all platforms where Chrome runs, as indicated by the generic CPE string with wildcard version matching.
RemediationAI
Vendor-released patch: Chrome 148.0.7778.96 and later. Users should update Chrome immediately via Settings > About Chrome, which typically triggers automatic download and installation. Enterprise administrators can manage deployments via the Omaha update service or platform-specific group policies. No workarounds are available for unpatched versions other than avoiding the use of untrusted media files. The primary mitigation is rapid patch deployment; enterprises should prioritize this update given the network accessibility of the attack vector, despite the UI:R requirement.
