CVE-2022-22706 Arm Mali Graphics Processing Unit (GPU): memory-safety flaw
In plain words: The program mishandles the memory it uses to keep track of data. A specially made input can scramble that memory. Usually lets an attacker crash the program or run their own code with its permissions.
Confirmed exploited by CISA on · US federal patch deadline Apr 20, 2023
What to do
- Install Arm's security update for Mali Graphics Processing Unit (GPU). If no update exists, follow the vendor's workaround or stop using the product until one ships.
- Install system updates the day they come out — most phone zero-days are fixed in a point release.
- Restart your phone every few days; some spyware does not survive a reboot.
- If you are a journalist, activist, lawyer, politician or executive, turn on Lockdown Mode (iPhone) or Advanced Protection (Android).
