CVE-2024-53165
📋 TL;DR
A use-after-free vulnerability in the Linux kernel's SH architecture interrupt controller allows attackers to potentially crash the system or execute arbitrary code with kernel privileges. This affects systems running Linux kernels with SH architecture support, primarily embedded devices and older hardware platforms.
💻 Affected Systems
- Linux kernel

Worst Case
Kernel panic leading to system crash or arbitrary code execution with kernel privileges, potentially resulting in complete system compromise.
Likely Case
System instability, kernel panic, or denial of service through controlled crashes.
If Mitigated
Minimal impact if proper kernel hardening and exploit mitigations are in place.
🎯 Exploit Status
Use-after-free vulnerabilities in kernel space are complex to exploit reliably but can lead to serious consequences.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Patched in stable kernel commits referenced in CVE
Vendor Advisory: https://git.kernel.org/stable/c/3c7c806b3eafd94ae0f77305a174d63b69ec187c
Restart Required: Yes
Instructions:
1. Update to a patched Linux kernel version containing the fix commits. 2. Reboot the system to load the new kernel.
🔧 Temporary Workarounds
Disable SH architecture support
linuxRemove or disable SH architecture support if not needed
# Recompile kernel without SH architecture support
🧯 If You Can't Patch
- Restrict local user access and implement strict privilege separation
- Enable kernel hardening features like KASLR, SMEP, SMAP if available
🔍 How to Verify
Check if Vulnerable:
Check kernel version and if SH architecture is enabled: 'uname -r' and check kernel config for CONFIG_SUPERHCheck Version:
uname -rVerify Fix Applied:
Verify kernel version is updated to include the fix commits or check that SH architecture is disabled📡 Detection & Monitoring
Log Indicators:
- Kernel panic logs
- Ooops messages in dmesg
- System crash reports
Network Indicators:
- None - local vulnerability only
