Samsung started rolling out the December 2021 security update to its smartphones a few days ago. However, the company had not revealed which vulnerabilities it had fixed with the new security patch. Now, the company has finally published all the details related to the December 2021 security patch.

The company has revealed that its December 2021 security patch includes 34 fixes from Google and ten fixes from Samsung. Seven of those fixes were for critical vulnerabilities, while 24 fixes were for high severity vulnerabilities. Samsung’s own fixes included in the new security patch are related to Broadcom’s Wi-Fi chipsets and Exynos processors running Android 9, Android 10, and Android 11.

Some bugs were related to Apps Edge, improper intent redirection handling in Tags, improper usage of implicit intent in SemRewardManager allowing attackers to access BSSID, improper input validation vulnerability in LDFW, improper access control vulnerability in CPLC, and improper validation vulnerability in FilterProvider. All these bugs were fixed by Samsung. You can check more details related to 34 fixes from Google on the search giant’s own website.

The December 2021 security update has been released to the Galaxy Z Flip, Galaxy Z Flip 5G, Galaxy S10, Galaxy Note 10, and the Galaxy Note 10+ 5G. The latest beta version of One UI 4.0 for the Galaxy Z Flip 3 and the Galaxy Z Fold 3 also includes the December 2021 security patch.
