A few days ago, a developer named Max Kellermann discovered a serious vulnerability in the Linux 5.8 kernel. You will find details about the vulnerability called Dirty Pipe in our previous note, and in this one we are talking about the fact that it affects all devices with an operating system based on the Linux kernel, such as Android smartphones / tablets, Google Home speakers, Chromecast and chromebooks.
“The Dirty Pipe vulnerability is extremely serious because it allows an attacker to overwrite – temporarily or permanently – files on the system that he should not be able to change,” Christoph Hebeisen, a security expert at Lookout, wrote in his report. “Attackers can use this to change the behavior of privileged processes, effectively gaining the ability to execute arbitrary code with extensive system privileges.”

According to his findings, Android 12 smartphones, including the Galaxy S22, Galaxy S21 FE, Google Pixel 6/Pixel 6 Pro, Oppo Find X5 and Realme 9 Pro+, are vulnerable. He was able to use the vulnerability to execute code and bypass security measures on the Pixel 6 smartphone.
He clarifies that the vulnerability only affects smartphones running Android 12 based on the Linux kernel version older than 5.8. At the moment, there are no signs that hackers actively exploited the vulnerability. Google is already preparing a patch to protect users.
