Google has released monthly security patches for Android that address 37 flaws across various components, one of which is a fix for an actively exploited Linux kernel vulnerability that was discovered earlier this year. The vulnerability, tracked as CVE-2021-22600 (CVSS score: 7.8), is rated “High” for severity and could be exploited by a local user to escalate privileges or deny service.

It’s worth noting that the vulnerability has also been added by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to its Known Exploited Vulnerabilities Catalog as of last month based on evidence of active exploitation. Also fixed as part of this month’s patches are three other bugs in the kernel as well as 18 high-severity and one critical-severity flaw in MediaTek and Qualcomm components.
