The vulnerability of the `copy_page_to_iter_pipe` and `push_pipe` functions in the Linux operating system allows a hacker to overwrite the contents of page cache for arbitrary files.

The vulnerability of the copypagetoiterpipe and pushpipe functions in the Linux operating system is related to errors in permission storage. Exploiting this vulnerability could allow an attacker to rewrite the contents of page cache for arbitrary files...

Dirty Pipe SUID Binary Hijack Privilege Escalation Exploit

Variant proof of concept exploit for the Dirty Pipe file overwrite vulnerability. This version hijacks a SUID binary to spawn a root shell. // // dirtypipez.c // // hacked up Dirty Pipe CVE-2022-0847 PoC that hijacks a SUID binary to spawn // a root shell. and attempts to restore the damaged bina...

Dirty Pipe Linux Privilege Escalation Exploit

Proof of concept for a vulnerability in the Linux kernel existing since version 5.8 that allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes. / SPDX-License-Identifier: GPL-2.0 / / Copyright 20...
