Samsung - Zero Day CVE

madasaf1sh — Sun, 14 Sep 2025 16:52:48 GMT

If you have a Samsung Phone running Android 13 or newer, get it updated, as Samsung have released an critical patch to fix a CVE which allows a attacker to run remote code on a unpatched (to the latest update) Samsung Phone or Tablet:

@madasaf1sh

Thank you very much for this information.

My last update installed was August 6th 2025.

I assume this will take the fix into account.

@TallTrees

It will be in Septembers Security update from the research I have done..

@madasaf1sh

Thank you .. It'll probably be in that.

My Samsung galaxy A70 only has infrequent updates last June 2024. 🤣

Had the August update but Septembers security update going off past updates will be around the 18th of the month so I will check again then

Cheers @madasaf1sh

Being an older model, the A70 won't be getting software or security updates anymore.

Hi @Spindle

Thank you.

It is a pity because it works perfectly and has an O2 paygo sim.

Anyway as advised .. it is checked with security device information in phone and regular scan. No downloads, or tricky apps don't need any. There were too many to start with.

It is still being used and enjoyed.

I think (maybe wrong) forces a new sale by withdrawing security patches then intimidating by saying unsafe. 🤔

Going forward with the A70 .. as long as possible 😊

The information I have, is a security update will be pushed to all Samsung phones running Android 13 or above...

Re: Samsung - Zero Day CVE

Spindle — Thu, 18 Sep 2025 10:41:52 GMT

Having a little read and it seems that this vulnerability only affects Android 13 or later.

As your phone is Android 11 it won't affect you anyway.

Spindle — Thu, 18 Sep 2025 10:46:56 GMT

I do hope you're right.

I no longer get updates since the 1st October 2024 security patch, and I'm on Android 13 😬

Re: Samsung - Zero Day CVE

TallTrees — Thu, 18 Sep 2025 11:23:55 GMT

Yes @Spindle

Maybe you will get an update all be it later 🤞

A70 is Android 11 (open to every attack known to man 🤣 )

But my contract phone is Android 15 😕

Best wishes

Hi @Cleoriff

My Samsung Android running 15

Updated 6th August 2025

So waiting for security patch now

Re: Samsung - Zero Day CVE

jonsie — Thu, 18 Sep 2025 18:42:37 GMT

@TallTrees @jonsie

I remember when I had my first Samsung smartphone and it told me it needed to update.

I left it for a week before I dare press the install now button 😂🤣

Oh those were the days when I was a real technophobe 😂

Re: Samsung - Zero Day CVE

TallTrees — Fri, 19 Sep 2025 08:22:35 GMT

Too true, often upset phone @Cleoriff

New updates were dreaded 😂

The days of having to do a factory reset are thankfully long gone
