Google details in a security bulletin what awaits owners of an Android smartphone in December 2021: a patch that addresses 47 vulnerabilities affecting several versions of the mobile operating system.
This is the last big patch of the year for Android. In the coming weeks, owners of a smartphone running the Google OS will gradually have access to the most recent patches for the mobile operating system, in order to immunize them against certain computer attacks. the security bulletin which describes the corrected vulnerabilities is provided: there are more than 45 security vulnerabilities.
A significant number, but that should be qualified: the Google report does not say that these vulnerabilities are being exploited by malicious third parties. If this was the case, it is certain that the American company would release an emergency patch to plug the breach, outside of its usual schedule of patch distribution.
Published on December 6, 2021, the report also details the level of severity of the bugs, with a scale ranging from “moderate” (with three problems) to “critical” (six). At the “severe” level, Google counts thirty-eight incidents. Many compartments of Android are affected: the system, the kernel, third-party components provided by manufacturers such as MediaTek or Qualcomm, etc.
Flaws affecting Android 9 to Android 12
The assessment of the severity of computer vulnerabilities follows an objective scale, called the score CVSS. It is used to qualify a flaw according to its characteristics: the more points it gains in the CVSS score, the more dangerous it is. Having physical access to the smartphone to hack it, for example, earns fewer points than an attack that can occur from a distance, because it is a little easier to set up.
Who is affected by the patch note? Anyone with a version of Android at least higher than 9, which was released in August 2018 – people using an older branch of the system can also be, if they are eligible for an update to Android 9 or higher . Individuals running Android 10 (September 2019), 11 (September 2020) and 12 (October 2021) are also concerned.
Depending on which version of Android you’re using, you won’t necessarily have to download and install all of the 47 vulnerabilities that Google has identified – some are only for certain branches. In any case, you will have nothing to do, except to accept the update when it presents itself to you within a few weeks, according to the update schedule of the manufacturer of your smartphone.
