The Dirty Pipe Vulnerability — The Dirty Pipe Vulnerability documentation
The Dirty Pipe Vulnerability — The Dirty Pipe Vulnerability documentation
This is the story of CVE-2022-0847, a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes. It is similar to CVE-2016-5195 “Dirty Cow” but is easier to exploit. The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.

Move, Patch, Get Out the Way: 2022 Zero-Day Exploitation Continues at an Elevated Pace
  • Mandiant tracked 55 zero-day vulnerabilities that we judge were exploited in 2022. Although this count is lower than the record-breaking 81 zero-days exploited in 2021, it still represents almost triple the number from 2020. * Chinese state-sponsored cyber espionage groups exploited more zero-days than other cyber espionage actors in 2022, which is consistent with previous years. * We identified four zero-day vulnerabilities exploited by financially motivated threat actors. 75% of these instances appear to be linked to ransomware operations. * Products from Microsoft, Google, and Apple made up the majority of zero-day vulnerabilities in 2022, consistent with previous years. The most exploited product types were operating systems (OS) (19), followed by browsers (11), security, IT, and network management products (10), and mobile OS (6).
