After updating nearly a dozen devices with the January 2020 security patch between late December and the start of this week, Samsung has detailed the vulnerabilities that have been fixed with the latest patch. The January 2020 patch fixes five critical vulnerabilities discovered in the Android operating system, along with a number of high and moderate-risk vulnerabilities.It also fixes 17 Samsung Vulnerabilities and Exposures (SVE) items, which are vulnerabilities that are specific to Galaxy smartphones and tablets. One of the most severe vulnerabilities among those allowed brute force attacks on the lock screen password on devices with the Exynos 7885, Exynos 8895, and Exynos 9810 chipsets under the hood. Apparently, this vulnerability had first been fixed all the way back in May last year but required a more concrete solution, which has been included in the January 2020 patch.As mentioned above, Samsung has already updated a few devices with the latest security patch, and more Galaxy phones and tablets will get it through updates in the coming weeks.
