By Google has revealed that a security flaw that was patched as part of a software update rolled out last week to its Chrome browser has come under active exploitation in the wild.
Tracked as CVE-2024-7965, the vulnerability has been described as an inappropriate implementation bug in the V8 JavaScript and Web Assembly engine.
Chrome Security Flaw Under Active Exploitation
“Inappropriate implementation in V8 in Google Chrome prior to 128.0.6613.84 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page,” according to a description of the bug in the NIST National Vulnerability Database (NVD).
A security researcher who goes by the online pseudonym The Dog has been credited with discovering and reporting the flaw on July 30, 2024, earning them a bug bounty of $11,000.
Additional specifics about the nature of the attacks exploiting the flaw or the identity of the threat actors that may be utilizing it have not been released. The tech giant, however, acknowledged that it’s aware of the existence of an exploit for CVE-2024-7965.
It also said, “in the wild exploitation of CVE-2024-7965 […] was reported after this release.” That said, it’s currently not clear if the flaw was weaponized as a zero-day prior to its disclosure last week.
The Hacker News has reached out to Google for further information about the flaw, and we will update the story if we hear back.
