Google released a new Chrome update on Thursday to fix the fourth zero-day vulnerability in two weeks and eighth overall in 2024.
“Google is aware that an exploit for CVE-2024-5274 exists in the wild,” the company said in an advisory. Google did not provide details on the bug or the exploitation but credited Clement Lecigne of Google’s Threat Analysis Group (TAG) and Brendon Tiszka of Chrome Security for reporting the flaw. There is no knowledge of any bug bounty reward for this discovery. “Successful exploitation of this vulnerability could allow for arbitrary code execution in the context of the logged on user,” the Center for Internet Security explained. Depending on the privileges associated with the logged on user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have less rights on the system could be less impacted than those who operate with administrative user rights.” Chrome vulnerabilities are often targeted by commercial spyware vendors. Google TAG researchers have previously reported several zero-days exploited by spyware vendors, including security defects in Google’s browser. CVE-2024-5274 is the fourth zero-day patched in the last 15 days, following CVE-2024-4671 (use-after-free in Visuals), CVE-2024-4761 (out-of-bounds write in V8), and CVE-2024-4947 (type confusion in V8). So far this year, Google has resolved a total of eight Chrome zero-days. Three of these, CVE-2024-2886, CVE-2024-2887, and CVE-2024-3159, were demonstrated at the Pwn2Own Vancouver 2024 hacking contest in March. Complete list of zero-days published in 2024:
