CVE-2024-52332

Q: What is the severity of CVE-2024-52332?

CVE-2024-52332 has a CVSS score of 7.1 (HIGH). This vulnerability in the Linux kernel's igb network driver could allow invalid memory access when the driver fails to initialize properly. It affects systems using the igb driver for Intel Gigabit Ethernet adapters. The issue occurs during module initialization when pci_register_driver() fails but cleanup isn't performed correctly.

7.1 HIGH

Denial of Service

📋 TL;DR

This vulnerability in the Linux kernel's igb network driver could allow invalid memory access when the driver fails to initialize properly. It affects systems using the igb driver for Intel Gigabit Ethernet adapters. The issue occurs during module initialization when pci_register_driver() fails but cleanup isn't performed correctly.

💻 Affected Systems

Products:

Linux kernel with igb driver

Versions: Specific affected kernel versions not specified in CVE, but patches exist for multiple stable branches

Operating Systems: Linux distributions using vulnerable kernel versions

Default Config Vulnerable: ⚠️ Yes

Notes: Only affects systems using Intel Gigabit Ethernet adapters with the igb driver loaded. The vulnerability triggers during module initialization failure.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Kernel panic or system crash leading to denial of service, potentially allowing privilege escalation if combined with other vulnerabilities.

🟠

Likely Case

System instability or crash when loading the igb driver module, resulting in denial of service for affected network interfaces.

🟢

If Mitigated

Driver initialization failure without system-wide impact if proper error handling is implemented.

🌐 Internet-Facing: LOW - Requires local access to trigger during driver initialization.

🏢 Internal Only: MEDIUM - Could affect servers during boot or driver reload, but requires local access or specific conditions.

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ✅ No

Complexity: MEDIUM

Exploitation requires ability to trigger driver initialization failure, typically requiring local access and specific conditions. No known public exploits.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Multiple stable kernel versions with fixes (see references)

Vendor Advisory: https://git.kernel.org/stable/c/0566f83d206c7a864abcd741fe39d6e0ae5eef29

Restart Required: No

Instructions:

1. Update Linux kernel to patched version. 2. For distributions: Use package manager (apt/yum/dnf) to update kernel package. 3. Rebuild kernel if using custom kernel with affected igb driver code.

🔧 Temporary Workarounds

Prevent igb module loading

Linux

Blacklist the igb driver module to prevent loading

echo 'blacklist igb' >> /etc/modprobe.d/blacklist-igb.conf
update-initramfs -u

🧯 If You Can't Patch

Avoid loading igb driver module unless necessary
Monitor system logs for igb initialization failures and restart affected services

🔍 How to Verify

Check if Vulnerable:

Check kernel version and if igb module is loaded: lsmod | grep igb && uname -r

Check Version:

uname -r

Verify Fix Applied:

Verify kernel version is updated beyond patched versions referenced in CVE

📡 Detection & Monitoring

Log Indicators:

Kernel panic messages
igb driver initialization failures in dmesg
PCI registration errors

Network Indicators:

Loss of network connectivity on igb interfaces

SIEM Query:

source="kernel" AND ("igb" OR "pci_register_driver") AND ("fail" OR "panic" OR "error")
