A noble gesture from the Korean brand that highlights the importance of being up to date.
A policy that becomes more important when it has been discovered that a good number of the brand’s televisions are affected by a vulnerability which can make it easier for an attacker to take control of the television. This is what is known so far and so you can check if yours is at risk.

With this practice, it could be done from a simple installation of an application, installing malware oheven steal any type of datafrom information that is entered in the browser to knowing what we are seeing.
According to the security company, there are more than 90,000 televisions (of which 963 are in Spain) that they have discovered thanks to Shodan, the search engine for devices connected to the Internet. Specifically, this flaw affects versions 4 to 7 of WebOS that run on LG televisions and the positive part is that to exploit the security gap, both the attacker and the television must be connected to the same WiFi network. These are the located gaps:
- webOS 4.9.7 – 5.30.40 running on LG43UM7000PLA
- webOS 5.5.0 – 04.50.51 running on OLED55CXPUA
- webOS 6.3.3-442 (kisscurl-kinglake) – 03.36.50 running on OLED48C1PUB

The models that are affected due to the security flaw are the LG43UM7000PLA, OLED55CXPUA, OLED48C1PUB and OLED55A23LA. If you want to know if your television is one of those affected, you can check the label on the back of the television or in the television settings, in its information.
The positive part is that BitDefender informed LG of the discovery at the end of 2023 and it has been responsible for launching the appropriate update that allows the vulnerability to be corrected. If your television is one of the most affected, you will soon have to receive the update that corrects it, you will have to receive the update that corrects it.
