CVE-2024-35828: wifi: libertas: fix some memleaks in lbs_allocate_cmd_buffer()

In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: fix some memleaks in lbs_allocate_cmd_buffer() In the for statement of lbs_allocate_cmd_buffer(), if the allocation of cmdarray[i].cmdbuf fails, both cmdarray and cmdarray[i].cmdbuf needs to be freed. Otherwise, there will be memleaks in lbs_allocate_cmd_buffer().

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue is a memory leak in the libertas Wi-Fi driver command-buffer allocation path. If an allocation fails, cleanup was incomplete. The business concern is mainly reliability and patch hygiene for affected Linux fleets, not a confirmed breach scenario. No source in the bundle reports active exploitation.

Executive priority

Treat this as routine kernel maintenance unless affected Wi-Fi-enabled embedded systems are operationally critical. It does not currently justify emergency response based on the supplied evidence.

Technical view

CVE-2024-35828 fixes missing frees in lbs_allocate_cmd_buffer() in the Linux kernel libertas Wi-Fi driver. The CVE record lists affected Linux kernel versions and stable commit references. No CVSS, CWE, exploit details, or KEV listing are provided in the bundle.

Likely exposure

Exposure appears limited to Linux systems running affected kernel builds where the libertas Wi-Fi driver is present or reachable. Products using vendor-maintained kernels may be affected through backported code, so version checks alone may be insufficient.

Exploitation context

The provided sources describe a memory leak during allocation-failure handling. They do not identify a remote attack path, privilege requirement, proof of exploitation, or weaponized exploit. CISA KEV status is false in the bundle.

Researcher notes

The key uncertainty is reachability. The bug is in cleanup after cmdbuf allocation failure, so validation should focus on affected code presence and vendor backports. The sources do not support claims about exploitability beyond memory leakage.

Mitigation direction

  • Update affected Linux kernels through the distribution or device vendor channel.
  • Prioritize systems using libertas Wi-Fi hardware or embedded Linux images.
  • Review Debian LTS and Siemens advisories if those environments apply.
  • Confirm vendor kernels include the referenced stable fixes.
  • Monitor vendor guidance for corrected package versions.

Validation and detection

  • Inventory Linux kernel versions across servers, endpoints, and embedded devices.
  • Check whether the libertas driver is built, loaded, or shipped.
  • Confirm fixed stable commits are present or backported by the vendor.
  • Review package changelogs for CVE-2024-35828 references.
  • Track exceptions where vendor status remains unclear.
