Impact
A use‑after‑free flaw exists in Chrome’s Autofill component on Windows, and it can be triggered by a crafted HTML page when a user is persuaded to perform specific UI gestures. The flaw can corrupt heap memory, potentially allowing an attacker to execute arbitrary code on the affected machine. Additionally, the vulnerability involves improper resource cleanup (CWE‑825) that exacerbates the heap corruption. The description explicitly states that the vulnerability is of critical severity, but the exact downstream exploits are not enumerated in the official advisory.
Affected Systems
Google Chrome running on Windows, versions prior to 149.0.7827.103. Users of older Chrome builds are impacted until they upgrade to 149.0.7827.103 or later.
Risk and Exploitability
The flaw is rated as high severity with a CVSS score of 7.5 and an EPSS score of <1%, indicating a low probability of exploitation; moreover, it is not listed in the CISA KEV catalog. The required attack vector involves a remote attacker delivering a specially crafted HTML page and convincing a user to interact with it. The exploit depends on user activity but could be delivered via phishing or malicious sites. Due to the high severity of the use‑after‑free, the risk, if the conditions are met, is significant. The issue also includes improper resource cleanup (CWE‑825), potentially exacerbating memory corruption.
