"As Nasty as Dirty Pipe" — 8 Year Old Linux Kernel Vulnerability Uncovered
Details of an eight-year-old security vulnerability in the Linux kernel have emerged that the researchers say is "as nasty as Dirty Pipe." Dubbed DirtyCred by a group of academics from Northwestern University, the security weakness exploits a previously unknown flaw CVE-2022-2588 to escalate...
CVE-2022-2590
A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write COW breakage of private read-only shared memory mappings. This flaw allows an unprivileged, local user to gain write access to read-only memory mappings, increasing their privileges on the system...

GHSA-JMWX-R3GQ-QQ3P vec-const attempts to construct a Vec from a pointer to a const slice
Affected versions of this crate claimed to construct a const Vec with nonzero length and capacity, but that cannot be done because such a Vec requires a pointer from an allocator. The implementation was later changed to just construct a std::borrow::Cow...

Linux “Dirty Pipe” vulnerability gives unprivileged users root access
A vulnerability in the Linux kernel, nicknamed "Dirty Pipe", allows an unprivileged user to overwrite data in read-only files. This can lead to privilege escalation as a result of unprivileged processes being able to inject code into root processes. If youre not sure what that means but you think...
Researchers Warn of Linux Kernel 'Dirty Pipe' Arbitrary File Overwrite Vulnerability
Linux distributions are in the process of issuing patches to address a newly disclosed security vulnerability in the kernel that could allow an attacker to overwrite arbitrary data into any read-only files and allow for a complete takeover of affected systems. Dubbed "Dirty Pipe" CVE-2022-0847,...

mm: don't try to NUMA-migrate COW pages that have other uses This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.10.102 by commit...
Security Bulletin: Vulnerability in Linux Kernel affects ProtecTIER: Dirty COW vulnerability (CVE-2016-5195)
Summary A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write COW breakage of private read-only memory mappings. An attacker could exploit this vulnerability to gain write access to read-only memory mappings and elevated privileges on the system...
Exploit for Race Condition in Canonical Ubuntu_Linux
This is a PoC Proof of Concept exploit for CVE-2016-5195, also known as Dirty COW. The exploit relies on ptrace to patch the vDSO Virtual Dynamic Shared Object and create a TCP reverse shell to the attacker's machine. The target of the exploit is the Linux kernel, and the vulnerability class is a...

GHSA-M7W4-8WP8-M2XQ Data races in beef
An issue was discovered in the beef crate before 0.5.0 for Rust. Affected versions of this crate did not have a T: Sync bound in the Send impl for Cow. This allows users to create data races by making Cow contain types that are Send && !Sync like Cell or RefCell. Such data races can lead to memor...
