CVE-2024-27068: thermal/drivers/mediatek/lvts_thermal: Fix a memory leak in an error handling path

In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/mediatek/lvts_thermal: Fix a memory leak in an error handling path If devm_krealloc() fails, then 'efuse' is leaking. So free it to avoid a leak.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel memory leak in the MediaTek LVTS thermal driver error path. If a kernel memory reallocation fails, memory allocated for efuse data is not freed. The business risk appears limited without evidence of active exploitation, but affected Linux builds should still take the vendor stable fix through normal kernel patching.

Executive priority

Handle through routine kernel patch management unless MediaTek-based Linux devices are business-critical or internet-exposed. There is no supplied evidence of active exploitation, but kernel memory leaks can affect reliability and should not be ignored.

Technical view

CVE-2024-27068 resolves a leak in thermal/drivers/mediatek/lvts_thermal. The issue occurs when devm_krealloc() fails and the efuse allocation is not freed. The CVE record provides kernel.org stable commits as references, but no CVSS, CWE, exploitability detail, or complete operational impact is supplied.

Likely exposure

Likely exposure is Linux kernels that include or run the MediaTek LVTS thermal driver. This is most relevant to MediaTek-based platforms. The source bundle does not prove exposure for generic Linux servers, distributions, or non-MediaTek hardware.

Exploitation context

No active exploitation is indicated. The CVE is not in KEV, and the supplied sources do not describe public exploitation, exploit primitives, or attacker requirements. Treat exploitation likelihood as unproven from the available evidence.

Researcher notes

The record describes a narrow error-path leak on devm_krealloc() failure. Severity metadata is incomplete: no CVSS, CWE, or detailed threat model is provided. Focus validation on code lineage, kernel backports, and whether the lvts_thermal driver is present in deployed builds.

Mitigation direction

  • Update to a vendor kernel containing the referenced stable fixes.
  • Prioritize MediaTek-based systems using the LVTS thermal driver.
  • Check distribution advisories for backported kernel fixes.
  • Do not deploy direct kernel.org patches without vendor compatibility review.

Validation and detection

  • Inventory Linux kernel versions across MediaTek-based systems.
  • Confirm whether the MediaTek LVTS thermal driver is built or loaded.
  • Map installed kernels to vendor advisories or referenced stable commits.
  • Verify patched test systems boot and thermal monitoring still works.
