How CVE-2025-31245 Works
This vulnerability allows a malicious app to trigger a kernel panic, leading to unexpected system termination (crash). Improper input validation in the IOKit subsystem enables an attacker to craft a malicious request that bypasses memory safety checks. When processed, this request causes a null pointer dereference or buffer overflow, crashing the kernel. The flaw affects multiple Apple platforms due to shared kernel code. Exploitation requires user interaction (running a malicious app), but no privileges are needed.
DailyCVE Form
Platform: macOS/iOS/tvOS/visionOS
Version: Sonoma 14.7.5 and below
Vulnerability: Kernel panic via IOKit
Severity: Critical
Date: 05/27/2025
Prediction: Patch by 06/10/2025
What Undercode Say:
Analytics:
- Attack vector: Local (malicious app)
- Exploitability: High (low complexity)
- Impact: DoS, potential RCE chain
Exploit Commands:
Crash PoC (IOKit trigger) ioreg -l | grep "ExploitableDevice"
// Kernel panic trigger (simplified)
include <IOKit/IOKitLib.h>
io_service_t service = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("IOSurfaceRoot"));
IOConnectCallMethod(service, 0xdeadbeef, ...); // Invalid selector
Protection Commands:
Check patch status sw_vers | grep "Version" Mitigation (disable vulnerable drivers) sudo kextunload -b com.apple.iokit.IOSurface
Patch Verification:
Post-update check system_profiler SPSoftwareDataType | grep "Kernel Version"
Detection Rules (YARA/Snort):
rule apple_iokit_panic {
strings: $ioservice_call = "IOConnectCallMethod"
condition: $ioservice_call and uint32(0) == 0xdeadbeef
}
