lsb_release -a
You should see 2024.2 or higher.
If you want to verify that your system is secure, run the following commands in your Kali terminal:
sudo apt update && sudo apt upgrade -y
dpkg -l | grep libc6
uname -r
You are looking for libc6 version 2.38-13 or higher, and kernel 6.6.9-kali1 or newer. These versions contain the official Cilocks remediation.
For penetration testers and security professionals, Kali Linux serves as the quintessential Swiss Army knife. A common workflow during engagements—particularly in Active Directory environments—is mounting remote SMB/CIFS shares to enumerate data exfiltration targets or analyze file permissions locally.
However, users frequently encounter a frustrating issue where the mount.cifs (or cifsmount) utility is broken or missing following a system update. This is often due to a package conflict or a necessary removal by the Kali development team to resolve dependency issues. This piece covers the context of this issue and the "patch" process to restore full SMB mounting capabilities.
The phrase "Kali Linux cilocks patched" can be interpreted in two ways: kali linux cilocks patched
Let’s examine both.
A: Absolutely not. The Certified Ethical Hacker (CEH) exam tests knowledge of aircrack-ng, not third-party wrappers. Learning Cilocks would be a waste of time and potentially unethical if misused.
By early 2024, reports began surfacing on GitHub and Kali Linux forums. Users noted that systems running Cilocks would:
Then came the critical revelation: Cilocks contained a memory leak and an unchecked buffer overflow in its deauthentication packet generator.
The original Cilocks script called mdk4 with a high packet rate parameter (-s 1000). However, it failed to implement proper rate limiting or error handling on the return values from the wireless stack. When a target AP did not respond (e.g., due to being out of range or already down), Cilocks entered an infinite loop of sending null frames. lsb_release -a
Specifically, the flawed code snippet looked like this (simplified):
while true; do
mdk4 $interface d -b $bssid -c $channel
done
Without a timeout or a check for stdout/stderr errors, mdk4 would spam the kernel’s network stack with malformed packets. On Kali Linux kernel versions 6.1.x and above, this triggered a buffer overflow in the mac80211 subsystem, leading to a kernel panic.
In layman’s terms: Cilocks wasn’t just attacking the target—it was attacking the attacker’s own machine.
The "patch" for this environment issue involves reinstalling the necessary userspace tools and ensuring the kernel helper modules are active.
Step 1: Update and Install cifs-utils
The core utility is contained within the cifs-utils package. Open a terminal and execute: You should see 2024
sudo apt update
sudo apt install cifs-utils
If the package was previously installed but broken, force a reinstallation:
sudo apt install --reinstall cifs-utils
Step 2: Verifying Kernel Modules
While cifs-utils provides the userspace tool, the kernel requires the cifs module to handle the actual filesystem protocol.
Check if the module is loaded:
lsmod | grep cifs
If it returns nothing, load the module manually:
sudo modprobe cifs
