Google fixes seventh Chrome zero-day exploited in attacks this year
Google has released an emergency security update for the Chrome desktop web browser to address a single vulnerability known to be exploited in attacks.
The company doesn’t provide many details about the vulnerability for security reasons, allowing Chrome’s user base enough time to update the web browser to version 107.0.5304.87/88, which addresses the problem.
“Access to bug details and links may be kept restricted until a majority of users are updated with a fix,” Google says.
“We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven’t yet fixed.”
In general, type confusion vulnerabilities occur when the program allocates a resource, object, or variable using a type and then accesses it using a different, incompatible type, resulting in out-of-bounds memory access.
By accessing memory regions that shouldn’t be reachable from the context of the application, an attacker could read sensitive information of other apps, cause crashes, or execute arbitrary code.
Google does not clarify the level of activity involving the exploit that exists in the wild, so whether attacks using CVE-2022-3723 are widespread or limited is not known at this time.
Chrome users can update their browser by opening Settings → About Chrome → Wait for the download to finish → Restart the program.
Seventh Chrome zero-day fixed this year
Version 107.0.5304.87/88 fixes the seventh zero-day vulnerability fixed since the start of the year.
Hence, Chrome users are strongly advised to update their web browsers as soon as possible to block exploitation attempts.
