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.

[CVE-2023-42752] integer overflow in Linux kernel leading to exploitable memory access
I recently found an integer overflow in the Linux kernel, which leads to the kernel allocating skb_shared_info in the userspace, which is exploitable in systems without SMAP protection since skb_shared_info contains references to function pointers.

Reptile Malware Targeting Linux Systems
Reptile Malware Targeting Linux Systems
Reptile is an open-source kernel module rootkit that targets Linux systems and is publicly available on GitHub. [1] Rootkits are malware that possess the capability to conceal themselves or other malware. They primarily target files, processes, and network communications for their concealment. Reptile’s concealment capabilities include not only its own kernel module but also files, directories, file contents, processes, and network traffic. Unlike other rootkit malware that typically only provide concealment capabilities, Reptile goes a step further by offering a reverse...

Linux Kernel Exploit (CVE-2022-32250) with mqueue
Netfilter is a framework in the Linux kernel for implementing various networking-related tasks with user-defined handlers. Netfilter provides various functions for packet filtering, network address translation and port translation, and packet logging. Netfilter represents a set of hooks that allow other kernel modules to register callback functions in the kernel’s networking stack.
