BlackBerry rolled out the September Android security patch ahead of Samsung, but later is better than never and the latter kept its promise to the Galaxy S7 and S7 Edge users, who are now getting a new update that contains 66 patches from Google, but the South Korean company has also patched nine vulnerabilities of its own.
One of the security issues fund by Samsung is related to the SystemUI and it was discovered in June. This problem was caused by a null pointer dereference on fimg2d driver on devices powered by the Exynos 7420 chipset and the September security patch has fixed it. Also, there were eight other issues found by Samsung in its products, but the update that is slowly rolling out to owners of the Galaxy S7 and S7 Edge also contains 57 patches from Google, which will be available via SMR or OS upgrades, depending on regions and device models. Those who are impatient can head to their devices’ Settings menu and manually check for the availability of the update.
As for the September Security Update, it’s available in three patch levels, as follows:
2016-09-0: fixes for two Critical remote code execution vulnerabilities, lots of Elevation of Privilege vulnerabilities, some Information Disclosure vulnerabilities, and Denial of Service vulnerabilities;
2016-09-05: Everything contained in the 2016-09-01 patch, plus patches for kernel related Elevation of Privilege vulnerabilities, driver vulnerabilities related to Qualcomm, and Elevation of privilege vulnerabilities discovered in third-party drivers;
2016-09-06: All patches from the 2016-09-01 and 2016-09-05, plus two fixes – one for a Critical Elevation of Privilege vulnerability in the kernel shared memory subsystem and one for a vulnerability in a Qualcomm networking component.
The update released by Samsung carries a firmware version of XXU1BPHJ, and it also brings Samsung Cloud and the new Gallery app which have been introduced on the problematic Galaxy Note7.
