CVE-2024-38603: drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset()

In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action() fails, the irq vector is not freed, which leads to a memory leak. Replace the devm_add_action with devm_add_action_or_reset to ensure the irq vector can be destroyed when it fails.

Security readout for executives and security teams

Plain-English summary

CVE-2024-38603 is a Linux kernel driver bug where an interrupt resource may not be released if setup fails. The public record describes a memory leak, not remote code execution or privilege escalation. Business urgency is mainly for systems using the affected HiSilicon HNS3-related kernel driver path.

Executive priority

Treat as routine kernel hygiene unless critical infrastructure depends on affected HNS3 hardware. Patch through standard maintenance windows, with faster handling for exposed production systems using this driver path.

Technical view

The issue is in drivers/perf/hisi/hns3. pci_alloc_irq_vectors() can allocate an IRQ vector, but a failing devm_add_action() path did not free it. The fix replaces devm_add_action() with devm_add_action_or_reset() so cleanup runs when registration fails.

Likely exposure

Exposure appears limited to Linux systems with affected kernel builds and the HiSilicon HNS3 perf driver path. The bundle lists Linux kernel versions and stable commits, but does not provide distribution-specific package mappings.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. The described impact is a memory leak on an error path. No public source here supports treating this as remotely exploitable or weaponized.

Researcher notes

Evidence is limited to the Linux kernel CVE text and stable commit references. The record lacks CVSS, CWE, exploitability detail, and distribution status. Analysis should avoid extending impact beyond the documented IRQ vector cleanup leak.

Mitigation direction

  • Update to a vendor-supported kernel containing the referenced stable fixes.
  • Check Linux distribution advisories for backported CVE-2024-38603 fixes.
  • Prioritize hosts using HiSilicon HNS3 hardware or related kernel modules.
  • Follow normal kernel update and reboot procedures for the platform.

Validation and detection

  • Inventory Linux kernel versions against vendor advisories for CVE-2024-38603.
  • Check whether HiSilicon HNS3-related drivers or hardware are present.
  • Confirm kernel changelogs include the CVE or referenced stable commits.
  • Monitor affected systems for resource exhaustion symptoms until patched.
