CVE-2022-50326: media: airspy: fix memory leak in airspy probe

In the Linux kernel, the following vulnerability has been resolved: media: airspy: fix memory leak in airspy probe The commit ca9dc8d06ab6 ("media: airspy: respect the DMA coherency rules") moves variable buf from stack to heap, however, it only frees buf in the error handling code, missing deallocation in the success path. Fix this by freeing buf in the success path since this variable does not have any references in other code.

Security readout for executives and security teams

Plain-English summary

This CVE is a Linux kernel memory leak in the Airspy SDR media driver. A temporary heap buffer allocated during device probing was not freed on the successful path. The sources do not provide a CVSS score, exploit evidence, or business-impact detail, so urgency depends mainly on whether affected kernels and Airspy-related driver exposure exist in your fleet.

Executive priority

Treat as a targeted kernel maintenance issue, not an emergency, unless your environment uses affected kernels with Airspy-related hardware or drivers. Because severity and exploitability are not established in the sources, fold remediation into normal kernel patch cycles after exposure is confirmed.

Technical view

A prior kernel change moved an Airspy probe buffer from stack to heap to respect DMA coherency rules. Error paths freed it, but the success path did not. The stable fixes free the buffer after successful probe because no other code keeps references to it.

Likely exposure

Exposure appears limited to Linux systems running affected kernel versions with the Airspy media driver present or loadable. The bundle lists Linux 6.0 through 6.0.3 and 6.1 as affected, but does not provide distribution-specific package mapping.

Exploitation context

No active exploitation is stated in the provided sources, and the CVE is not listed as KEV. The bundle describes a memory leak during successful driver probe, but provides no public exploitability analysis, attack prerequisites, or demonstrated impact.

Researcher notes

The core issue is a success-path cleanup omission introduced when buf moved to heap allocation. Analysis should focus on affected kernel provenance, driver reachability, and whether repeated probe events can create meaningful memory pressure. Source evidence is limited to CVE metadata and kernel stable commits.

Mitigation direction

  • Check Linux vendor advisories for patched kernel packages.
  • Upgrade to a kernel containing the referenced stable fixes.
  • Inventory systems with Airspy media driver support enabled.
  • Restrict unnecessary kernel modules where operationally feasible.

Validation and detection

  • Confirm running kernel versions against vendor fixed-version guidance.
  • Check whether the Airspy driver is present or loadable.
  • Review kernel package changelogs for the referenced stable commits.
  • Prioritize validation on hosts that attach SDR or USB radio devices.
