  • CISA Known Exploited Vulnerabilities (KEV) Status: CVE-2026-3909 is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) Catalog. CISA maintains this catalog as an authoritative source of vulnerabilities that have been exploited in the wild, and organizations are advised to use it as an input for their vulnerability management processes [2].
  • Evidence of Active Exploitation: There is evidence of active exploitation of CVE-2026-3909 in the wild. Google has released security updates to address this vulnerability, and the company is aware of attacks exploiting it [3].
  • Internet-Facing Applications or Services: The vulnerability affects Google Chrome [3], specifically an "Out of bounds write in Skia" [1]. While Chrome is a widely used application, the direct impact on internet-facing *services* would depend on how Chrome is used to access them. The vulnerability allows a remote attacker to perform out-of-bounds memory access via a crafted HTML page [1].
  • Attack Vectors and Exploitation Methods: The attack vector is identified as Network, with Low Attack Complexity and No Privileges Required. The vulnerability can be exploited by a remote attacker through a crafted HTML page [1].
  • Targeted Attacks: While the vulnerability is being actively exploited, the provided information does not specify whether it has been used in targeted attacks.
  • Technical Details about Internet Exploitability: The vulnerability is an out-of-bounds write in Skia within Google Chrome, affecting versions prior to 146.0.7680.75 [1]. This type of vulnerability can lead to memory corruption, potentially allowing an attacker to execute arbitrary code or cause a denial-of-service condition. The exploitability via a crafted HTML page suggests that a user visiting a malicious website or opening a malicious HTML document in Chrome could be affected.
