Samsung March 2023 update brings important patch to Galaxy S21 Exynos models
Samsung recently released its March 2023 security update details, which mention fixes for a lot of CVE and SVE items. In the meantime, the company also reveals an important vulnerability fix for Samsung Galaxy S21 Exynos models with the March 2023 patch.
The SVE that reads “SVE-2022-0604(CVE-2023-21459)” fixes the use after free vulnerability in the decon driver. This issue was allowing attackers to cause memory access faults, meanwhile, the March 2023 patch adds proper check logic to prevent use after free.
The security patch details further say that this moderate level of SVE was reported on February 1, 2023. It was affecting the Galaxy devices driving Android 11, Android 12, and Android 13 operating systems with the Exynos 2100 chipset.
The Samsung Galaxy S21 series phones, including the S21, S21+, S21 Ultra, and S21 FE, use Exynos 2100 chipset in select regions, which means the March 2023 patch has fixed this major vulnerability for all these devices.
‘Improper authorization in Exynos baseband’ is also resolved:
Aside from the decon driver exposure, Samsung has also fixed the improper authorization in the Exynos baseband vulnerability – SVE-2022-2678(CVE-2023-21455).
As per the information, this issue was affecting Samsung Exynos models. It was allowing incorrect handling of the unencrypted message as was reported in November last year.
It is worth noting that Samsung is yet to release the March 2023 Android security patch update for Galaxy S21, S21+, S21 Ultra, or S21 FE customers. In fact, it hasn’t started delivering the March patch update yet.
Usually, the Korean company does not delay the release of security patches, but since it is currently rolling out the One UI 5.1 update, we are seeing a delay. However, the release is not far away, Galaxy customers are likely to get the March 2023 security patch very soon.
Samsung’s Galaxy S21 FE now supports the Camera Assistant app. The company has silently brought this upgrade to one of its popular Fan Edition smartphones. However, some Camera Assistant features available in flagship phones don’t arrive on the S21 FE.
Folks over at SamMobile highlight that Camera Assistant support for Galaxy S21 FE went live in January this year. It’s worth noting that the Camera Assistant app received its last update in January, which probably made the S21 FE-supported model.
Camera Assistant is a free-to-download app available on the Galaxy Store. Support for S21 FE was initially planned to arrive with a One UI 6.0 upgrade. The company has also fulfilled its promise, while this significant development didn’t fall under our radar.
Once downloaded, you will be able to make changes to the stock camera application. Camera Assistant allows you to bring a 2x zoom button to the camera viewfinder, picture softening, burst shot when using the timer, distortion correction, and disable long press video recording.

Samsung Care+ is a stunning service that users can combine with the device while purchasing. In a recent development, Samsung announced Galaxy users will now be able to raise two claims per year.
The Samsung Care+ program now covers two claims per year in India. The new policy applies to all kinds of Care+ plans that include Accidental and Liquid Damage Protection and Screen Protection only. Previously, it covered two claims within two years.
It’s a pretty significant decision the company has taken given consumer satisfaction. We’ve observed cases of consumer dissatisfaction with authorized Samsung centers and staff assigned there. They either lack idea about the latest flagship products or delay unusually.
The company offers the Care+ subscription for free with flagship devices in select countries. Paying a one-time fee, you can raise a claim at authorized Samsung service centers.
It ensures your Galaxy device is repaired through an official channel at a minimal cost. Samsung’s Care+ program is available for smartphones, laptops, tablets, and other devices.
