Linux kernel Intel IPU6 CPU latency QoS use-after-free

IdentifiersCVE-2024-58004CWE-416

CVE-2024-58004 is a use-after-free condition in the Linux kernel Intel IPU6 media driver. On an error path, the driver could free memory associated with a CPU latency QoS request without first removing that request from the CPU latency QoS list. A subsequent QoS update can operate on the stale list entry, resulting in list corruption in the PM QoS subsystem.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Triggering the stale QoS request can corrupt kernel list state and produce kernel warnings or a crash, causing denial of service. Because the defect involves a freed object remaining reachable through a kernel list, it is a kernel memory-safety issue; the available information does not establish reliable privilege escalation or code execution.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by avoiding or disabling use of the affected intel/ipu6 functionality and related workflows that exercise the vulnerable error path, where operationally feasible. More generally, restrict access to local interfaces and hardware/driver functionality to trusted users and systems, since exploitation appears to depend on reaching the affected kernel driver path. No complete mitigation short of applying a fixed kernel is provided in the available information.

Remediation

Patch, then assume compromise.

Install a Linux kernel update containing the Intel IPU6 fix that removes the CPU latency QoS request on the relevant error path, then reboot into the updated kernel. Distribution-maintained kernel updates that incorporate this fix should be used.
