Security readout for executives and security teams
Plain-English summary
CVE-2024-35911 is a Linux kernel bug in the Intel ice network driver. After a system suspend and driver rebuild, the driver can corrupt memory and panic the kernel. The evidence points mainly to availability risk on systems using this driver, not confirmed remote compromise.
Executive priority
Handle in normal kernel maintenance cycles, with faster action for affected production hosts where suspend/resume or NIC rebuild instability could disrupt service. There is no sourced evidence of active exploitation, but kernel memory corruption warrants timely remediation.
Technical view
The ice driver could allocate a zero-length queue-vector buffer during rebuild because num_q_vectors was cleared during suspend and restored too late. Later code indexed the buffer using the restored value, causing kernel memory corruption and observed NULL pointer dereference during ice_service_task after suspend/resume.
Likely exposure
Exposure is most likely on Linux systems using Intel ice Ethernet hardware and affected kernel builds, especially where suspend/resume or driver rebuild paths occur. The source lists Linux kernel versions and stable fix commits, but distro backports must be checked separately.
Exploitation context
No provided source reports active exploitation, and KEV is false. The source evidence describes a crash during suspend/resume on Linux 6.8.0-rc1. Practical attacker control is not established in the bundle, so treat this as an operational stability and kernel memory-safety issue.
Researcher notes
The record describes a regression after commit b3e7b3a6ee92 and fixes code ordering around num_q_vectors restoration via ice_vsi_cfg_def(). Evidence is incomplete for exploitability beyond crash/memory corruption, so avoid claiming privilege escalation or remote attack without additional vendor analysis.
Mitigation direction
- Apply a kernel update containing the referenced stable ice driver fixes.
- Prioritize systems with Intel ice Ethernet adapters and suspend/resume usage.
- Check distribution advisories for backported fixes to supported kernels.
- If unpatched, review vendor guidance before changing suspend or driver behavior.
Validation and detection
- Inventory Linux kernel versions and systems loading the ice driver.
- Confirm whether referenced stable commits are present or backported.
- Review kernel logs for ice driver panics after suspend/resume.
- Test suspend/resume on representative patched hosts before broad rollout.
