CVE-2024-57998
📋 TL;DR
This CVE describes an out-of-bounds read vulnerability in the Linux kernel's Operating Performance Point (OPP) framework. An attacker could potentially read kernel memory beyond allocated bounds, leading to information disclosure or system instability. This affects all Linux systems using the OPP framework for frequency scaling.
💻 Affected Systems
- Linux kernel

Worst Case
Kernel memory disclosure leading to privilege escalation, system crash, or information leakage that could aid further attacks.
Likely Case
System instability, kernel panic, or denial of service due to invalid memory reads.
If Mitigated
Limited impact with proper kernel hardening and memory protection mechanisms in place.
🎯 Exploit Status
Requires local access and ability to trigger specific OPP framework functions. Likely requires root or privileged access to exploit effectively.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Kernel versions containing commits: 774dd6f0f0a61c9c3848e025d7d9eeed1a7ca4cd, 7d68c20638e50d5eb4576492a7958328ae445248, d659bc68ed489022ea33342cfbda2911a81e7a0d, da2a6acc73933b7812c94794726e438cde39e037, eb6ffa0192ba83ece1a318b956265519c5c7dcec
Vendor Advisory: https://git.kernel.org/stable/c/774dd6f0f0a61c9c3848e025d7d9eeed1a7ca4cd
Restart Required: Yes
Instructions:
1. Update to a kernel version containing the fix commits. 2. For distributions: Use package manager (apt/yum/dnf) to update kernel package. 3. Reboot system to load new kernel.
🔧 Temporary Workarounds
Disable OPP framework if not needed
LinuxRemove or disable OPP framework if frequency scaling is not required for your hardware.
echo 'blacklist opp' >> /etc/modprobe.d/blacklist.conf
update-initramfs -u
🧯 If You Can't Patch
- Restrict local user access and implement strict privilege separation
- Enable kernel hardening features like KASLR and memory protection
🔍 How to Verify
Check if Vulnerable:
Check kernel version and verify if OPP framework is loaded: lsmod | grep oppCheck Version:
uname -rVerify Fix Applied:
Check kernel version contains fix commits: uname -r and verify with distribution's security advisory📡 Detection & Monitoring
Log Indicators:
- Kernel oops messages
- System crashes related to OPP or frequency scaling
Network Indicators:
- None - local vulnerability only
