Official Description
Use-after-free vulnerability in the Element::normalizeAttributes function in dom/Element.cpp in WebCore in WebKit in Google Chrome before 5.0.375.70 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to handlers for DOM mutation events, aka rdar problem 7948784.

Technical Analysis
CVE-2010-2300 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2010-2300. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-416): Use-after-free vulnerabilities involve accessing memory after it has been freed, often enabling arbitrary code execution.
