CVE-2022-50143: intel_th: Fix a resource leak in an error handling path

In the Linux kernel, the following vulnerability has been resolved: intel_th: Fix a resource leak in an error handling path If an error occurs after calling 'pci_alloc_irq_vectors()', 'pci_free_irq_vectors()' must be called as already done in the remove function.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel resource leak in the Intel Trace Hub driver error path. If setup fails after IRQ vectors are allocated, the kernel failed to free them. The provided sources do not show active exploitation, CVSS, or broad impact details, so business urgency should be driven by normal kernel patch management.

Executive priority

Treat this as routine kernel maintenance unless internal exposure analysis finds sensitive systems on affected kernels. There is no provided evidence of exploitation or critical impact, but kernel fixes should still be absorbed through standard patch cycles.

Technical view

The fix adds cleanup after pci_alloc_irq_vectors() when later initialization fails in intel_th. The remove path already freed IRQ vectors; the vulnerable error path did not. Evidence only identifies Linux kernel affected versions and stable-tree fixes, without exploitability, privilege, or attack-vector details.

Likely exposure

Systems running affected Linux kernel builds with the Intel Trace Hub driver code present may be exposed. The source bundle lists Linux kernel versions and stable commit fixes, but does not map distribution packages or configurations.

Exploitation context

The provided sources do not indicate active exploitation, and the CVE is not marked KEV. No exploit method, attack vector, or required privileges are provided, so exploitation likelihood cannot be reliably assessed from this bundle.

Researcher notes

The weakness is a missing pci_free_irq_vectors() call on a probe error path after pci_alloc_irq_vectors(). The source bundle lacks CVSS, CWE, distro package mapping, and practical exploitability details, so conclusions should remain conservative.

Mitigation direction

  • Update affected Linux kernels through the normal distribution or vendor kernel channel.
  • Confirm the installed kernel includes one of the referenced stable fixes.
  • For custom kernels, backport the upstream stable patch for the relevant branch.
  • Reboot into the updated kernel after patching.
  • Monitor Linux distribution advisories for package-specific guidance.

Validation and detection

  • Inventory Linux kernel versions across servers and endpoints.
  • Check vendor changelogs for CVE-2022-50143 or the referenced commit IDs.
  • Verify the running kernel, not only the installed package, is updated.
  • Review whether Intel Trace Hub support is built or loaded where relevant.
