Q: What is the severity of CVE-2024-50007?

CVE-2024-50007 has a CVSS score of 7.8 (HIGH). This CVE describes an out-of-bounds array access vulnerability in the ASIHPI driver of the Linux kernel. An attacker could exploit this to cause kernel memory corruption, potentially leading to system crashes or privilege escalation. Systems running vulnerable Linux kernel versions with the ASIHPI driver loaded are affected.

📋 TL;DR

This CVE describes an out-of-bounds array access vulnerability in the ASIHPI driver of the Linux kernel. An attacker could exploit this to cause kernel memory corruption, potentially leading to system crashes or privilege escalation. Systems running vulnerable Linux kernel versions with the ASIHPI driver loaded are affected.

💻 Affected Systems

Products:

Linux kernel

Versions: Specific affected versions not explicitly stated in CVE, but patches are available in stable kernel trees

Operating Systems: Linux distributions using vulnerable kernel versions

Default Config Vulnerable: ✅ No

Notes: Only vulnerable if the ASIHPI sound driver is loaded/used. Many systems may not have this driver loaded by default.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Local privilege escalation to root, kernel panic causing system crash, or arbitrary code execution in kernel context.

🟠

Likely Case

Kernel panic leading to denial of service (system crash) or local privilege escalation if combined with other vulnerabilities.

🟢

If Mitigated

System remains stable with no impact if the driver is not loaded or the patch is applied.

🌐 Internet-Facing: LOW - This is a local kernel vulnerability requiring local access to exploit.

🏢 Internal Only: MEDIUM - Internal users with local access could potentially exploit this for privilege escalation or denial of service.

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ✅ No

Complexity: MEDIUM

Requires local access and knowledge of how to trigger the vulnerable code path in the ASIHPI driver.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Patches available in stable kernel trees (commits referenced in CVE)

Vendor Advisory: https://git.kernel.org/stable/c/219587bca2678e31700ef09ecec178ba1f735674

Restart Required: Yes

Instructions:

1. Update to a patched kernel version from your distribution's repositories. 2. Rebuild kernel if compiling from source with the fix. 3. Reboot system to load patched kernel.

🔧 Temporary Workarounds

Unload ASIHPI driver

linux

Remove the vulnerable driver module if not needed

sudo rmmod snd_asihpi
echo 'blacklist snd_asihpi' | sudo tee /etc/modprobe.d/blacklist-asihpi.conf

🧯 If You Can't Patch

Ensure the ASIHPI driver is not loaded (check with 'lsmod | grep asihpi')
Implement strict access controls to limit local user privileges

🔍 How to Verify

Check if Vulnerable:

Check if ASIHPI driver is loaded: 'lsmod | grep asihpi' and check kernel version against patched versions

Check Version:

uname -r

Verify Fix Applied:

Verify kernel version is updated and ASIHPI driver version includes the bounds check fix

📡 Detection & Monitoring

Log Indicators:

Kernel oops messages
System crash/panic logs
ASIHI driver error messages in dmesg

Network Indicators:

None - this is a local vulnerability

SIEM Query:

Search for kernel panic events or ASIHPI driver errors in system logs
