CVE-2024-53107
📋 TL;DR
This CVE describes an integer overflow vulnerability in the Linux kernel's pagemap_scan_get_args() function. An attacker with local access could trigger memory corruption by providing specially crafted input, potentially leading to denial of service or privilege escalation. All Linux systems using affected kernel versions are vulnerable.

Worst Case
Local privilege escalation to root, allowing complete system compromise and potential kernel panic/crash.
Likely Case
Kernel panic or system crash causing denial of service, requiring reboot to restore functionality.
If Mitigated
No impact if patched or if SELinux/AppArmor prevents access to the vulnerable interface.
🎯 Exploit Status
Requires local access and knowledge of kernel memory layout. No public exploit code identified in references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Kernel versions containing commits 669b0cb81e4e4e78cff77a5b367c7f70c0c6c05e or adee03f8903c58a6a559f21388a430211fac8ce9
Vendor Advisory: https://git.kernel.org/stable/c/669b0cb81e4e4e78cff77a5b367c7f70c0c6c05e
Restart Required: Yes
Instructions:
1. Update Linux kernel to patched version from your distribution vendor. 2. Reboot system to load new kernel. 3. Verify kernel version after reboot.
🔧 Temporary Workarounds
Restrict /proc access
linuxLimit access to /proc filesystem to prevent unauthorized users from triggering the vulnerability
chmod 750 /proc
setfacl -m u:username:rx /proc
Enable kernel hardening
linuxUse SELinux or AppArmor to restrict access to kernel interfaces
setenforce 1
apparmor_parser -r /etc/apparmor.d/*
🧯 If You Can't Patch
- Implement strict access controls to prevent unauthorized local users from accessing the system
- Monitor for unusual process behavior or kernel panic events in system logs
🔍 How to Verify
Check if Vulnerable:
Check kernel version and compare with distribution security advisories. Examine if /proc/task_mmu interface is accessible.Check Version:
uname -rVerify Fix Applied:
Verify kernel version contains the fix commits: 'uname -r' and check with distribution vendor for patched versions.📡 Detection & Monitoring
Log Indicators:
- Kernel panic messages in /var/log/messages or dmesg
- Unexpected process crashes
- Permission denied errors for /proc access
Network Indicators:
- No network indicators - local exploit only
SIEM Query:
source="kernel" AND ("panic" OR "Oops" OR "segfault") AND process="[kernel]"
