The first such problem to be fixed since the year’s beginning, Google fixed an actively exploited zero-day vulnerability in its Chrome web browser on Friday by releasing out-of-band upgrades.
“Type confusion in V8 in Google Chrome before 112.0.5615.121 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page,” according to the National Vulnerability Database (NVD) of NIST.
The tech giant admitted that “an exploit for CVE-2023-2033 exists in the wild.” Still, it refrained from disclosing additional technical details or indications of compromise (IoCs) to discourage threat actors from abusing the vulnerability.
In addition, CVE-2022-1096, CVE-2022-1364, CVE-2022-3723, and CVE-2022-4262, four other actively exploited type confusion problems in V8 that were fixed by Google in 2022, appear to be related to CVE-2023-2033.
Nine zero days in Chrome were successfully closed down by Google last year. The news comes days after Citizen Lab and Microsoft revealed that customers of the shady spyware vendor QuaDream were using a hole in Apple iOS that has since been patched to target journalists, members of the political opposition, and an employee of an NGO in 2021.
