CVE-2024-53053

5.5 MEDIUM

📋 TL;DR

A deadlock vulnerability in the Linux kernel's UFS (Universal Flash Storage) driver can cause system hangs when runtime power management operations conflict with RTC (Real-Time Clock) update work. This affects Linux systems using UFS storage devices. The vulnerability requires local access to trigger.

💻 Affected Systems

Products:
  • Linux kernel
Versions: Specific affected kernel versions not specified in CVE, but patches available for stable branches
Operating Systems: Linux distributions using affected kernel versions
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with UFS storage devices. Requires specific timing conditions during RTC updates and power management operations.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system deadlock requiring hard reboot, causing denial of service and potential data loss or corruption.

🟠

Likely Case

System becomes unresponsive when specific UFS power management operations occur during RTC updates, requiring manual intervention.

🟢

If Mitigated

Minor performance impact from avoiding the deadlock scenario with proper patching.

🌐 Internet-Facing: LOW - Requires local access to trigger, not remotely exploitable.
🏢 Internal Only: MEDIUM - Local users or processes could trigger system hangs affecting availability.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: NO
Unauthenticated Exploit: ✅ No
Complexity: HIGH

Requires local access and specific timing conditions. More of a reliability issue than security vulnerability, but can cause denial of service.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Patches available in stable kernel branches via provided git commits

Vendor Advisory: https://git.kernel.org/stable/c/9aa1f0da237d6b16e36e0a0cc9f746d1d78396ed

Restart Required: Yes

Instructions:

1. Update Linux kernel to patched version from your distribution. 2. Reboot system. 3. Verify kernel version after reboot.

🔧 Temporary Workarounds

Disable UFS runtime power management

linux

Prevent the deadlock by disabling runtime power management for UFS devices

echo 'on' > /sys/bus/platform/devices/*.ufs/power/control

🧯 If You Can't Patch

  • Monitor system for hangs and have reboot procedures ready
  • Consider disabling UFS devices if not critical for system operation

🔍 How to Verify

Check if Vulnerable:

Check kernel version and if UFS devices are present: ls /sys/bus/platform/devices/*.ufs

Check Version:

uname -r

Verify Fix Applied:

Verify kernel version is updated beyond patched commits and system operates normally during UFS operations

📡 Detection & Monitoring

Log Indicators:

  • Kernel panic messages
  • System hang reports
  • UFS driver error messages in dmesg

Network Indicators:

  • None - local issue only

SIEM Query:

Search for: 'kernel panic' OR 'system hang' OR 'UFS deadlock' in system logs
