Google has been releasing monthly security patches like clockwork ever since it revamped the Android security model in the wake of Stage Fright. Samsung and LG are also trying to keep up with the monthly patches, but not always with the most success. LG's getting the jump on Google today, though. It has posted the January security bulletin a little early with information onGoogle and LG-specific patches.
You can check LG's security page for the full list or patches (under the LG Security Bulletin tab). There are 81 total patches from Google and LG. Only eight of them are for LG devices only. LG's page links to the Google security bulletin page, but of course that still shows the December patch info. You can expect more detail on the Google patches when Mountain View gets around to posting its update next week. Some are already public and include things like arbitrary code execution and kernel privilege escalation flaws.
LG has descriptions of all its internal bugs, one of which is critical and involves user data leaking on MediaTek devices. The high and moderate level patches cover various privilege escalation vulnerabilities. These patches will be delivered todevices like theG3, G4, G4 Stylus, G5, V10, V20, CK, and G Stylo. There are no specifics on release date, which will vary by carrier and region.Source: LG
