This vulnerability, hidden within the netfilter: nf_tables component, allows local attackers to escalate their privileges and potentially deploy ransomware, which could severely disrupt enterprise systems worldwide.

I read: Microsoft started to feel threatened and paid black hats to exploit vulnerabilities in wares that people have recently learned are far superior to their goddamned surveillance garbage.

This only affects positively ancient kernels:

From (including) 3.15 Up to (excluding) 5.15.149 From (including) 6.1 Up to (excluding) 6.1.76 From (including) 6.2 Up to (excluding) 6.6.15 From (including) 6.7 Up to (excluding) 6.7.3

fuck my phone running android is vulnerable

If I’m not mistaken, RHEL9 and equivalents are on 5.15. That’s a pretty big blast radius.

[–] Brosplosion@lemmy.zip 3 points 6 days ago

RHEL is on 5.15 in spirit only. They backport tons of patches to the point that 5.15 modules don't build against it

[–] turdas@suppo.fi 8 points 1 week ago (1 children)

They will probably have a version newer than 5.15.149.

AliasAKA is correct, it’s actually 5.14, not 5.15 like I thought.

For exploiting a privilege escalation the attacker must be able to run their own code on your machine. If you let them do such things, you already have more than enough security problems in the first place.

[–] okamiueru@lemmy.world 13 points 1 week ago (1 children)

Except for supply chain attacks. You get a foot in the door, and open the rest with impunity

[–] Treczoks@lemmy.world 1 points 6 days ago (1 children)

Yes, but still a privilege elevation bug is still less risky than a remote execution one.

[–] JackbyDev@programming.dev 4 points 6 days ago

They're replying to the victim blaming mentality of "if you let them then you have bigger problems" in your comment. Not your point about it being less dangerous than remote execution.

Local attacker? So on your LAN

[–] henfredemars@infosec.pub 25 points 1 week ago (1 children)

You need to be able to run code on the system that has the bug. The bug is in the netfilter component, in how it's managed on that system, not in the actual traffic flows.

[–] BCsven@lemmy.ca 8 points 1 week ago (3 children)

So a non issue unless somebody has physical access to the machine?

[–] who@feddit.org 22 points 1 week ago* (last edited 1 week ago) (1 children)

Unfortunately, it's not that simple, because attacks often involve "exploit chains". In this case, an attacker would use a different vulnerability to gain code execution capability, and then use that capability to exploit this vulnerability.

Update your systems, folks.

And that kids, is why we are pushing for Rust in the Kernel

[–] onlinepersona@programming.dev 21 points 1 week ago

But... You dont understand, Rust is the devil! If Rust were made the kernel's main language it would terrible because that would mean change 😭😭😭

[–] Zangoose@lemmy.world 6 points 1 week ago

But then the kernel wouldn't be free! Free as in 'use-after-free'!

(/s in case it wasn't obvious)

Feeling pret-ty smug about my Windows 10 machine rn ngl

[–] Frenchgeek@lemmy.ml 18 points 1 week ago

Your Windows 10 machine? Microsoft disagree.

[–] prole@lemmy.blahaj.zone 7 points 1 week ago (4 children)

Lol because Windows has never been exploited
