Arm flaws being used in attacks

CISA lists 9 flaws in Arm products as being used in attacks, most recently on 12 Jun 2024.

What to do

1. Update every Arm product you use.Install the updates Arm offers, on every device, and restart when asked. Each flaw below has a fix or clear advice; that’s one of CISA’s conditions for listing it.
2. If someone looks after IT for you, send them this page.Many of these are in equipment you don’t see: routers, firewalls, servers, the office network. Ask them to confirm each one is fixed, or that you don’t use the product.
3. Check anything else in the lookup.Search any app, company or CVE. Not being on CISA’s list doesn’t mean safe: keep updating either way.
