CVE-2024-41028: platform/x86: toshiba_acpi: Fix array out-of-bounds access

In the Linux kernel, the following vulnerability has been resolved: platform/x86: toshiba_acpi: Fix array out-of-bounds access In order to use toshiba_dmi_quirks[] together with the standard DMI matching functions, it must be terminated by a empty entry. Since this entry is missing, an array out-of-bounds access occurs every time the quirk list is processed. Fix this by adding the terminating empty entry.

Security readout for executives and security teams

Plain-English summary

A Linux kernel Toshiba ACPI driver defect can read beyond an internal array whenever its hardware quirk list is processed. A locally authenticated, low-privilege user may be able to expose kernel memory or disrupt the system. The supplied CVSS score is 7.1, rated high.

Executive priority

Treat this as a high-priority kernel maintenance issue for affected endpoints, especially multi-user systems where untrusted local accounts exist. It does not warrant emergency internet-edge response because the documented attack vector is local and active exploitation is not established.

Technical view

The toshiba_dmi_quirks array lacked the empty terminating entry required by standard DMI matching functions. Processing the list consequently caused an out-of-bounds access. The upstream correction adds that terminator. The supplied CVSS vector indicates local, low-complexity exploitation requiring low privileges, with potentially high confidentiality and availability impact but no integrity impact.

Likely exposure

Exposure is limited to Linux kernels containing the vulnerable toshiba_acpi implementation and processing its DMI quirk list. The bundle identifies affected 6.1, 6.1.100, 6.6.41, 6.9.10, and 6.10 releases. Distribution backports may alter applicability, so package-level confirmation is necessary.

Exploitation context

The CVSS vector describes a local attack requiring low privileges and no user interaction. The CVE is not listed in KEV, and the supplied sources provide no evidence of active exploitation or a publicly weaponized exploit.

Researcher notes

The defect is a missing sentinel in a DMI match table, producing an out-of-bounds access whenever the quirk list is evaluated. Four stable-kernel commits are supplied, indicating branch-specific corrections. The sources do not establish the exact exposed data, crash behavior, practical exploit reliability, or active exploitation.

Mitigation direction

  • Apply a vendor-supported kernel update incorporating the relevant stable fix or an equivalent distribution backport.
  • Prioritize systems where the toshiba_acpi quirk list is processed.
  • If updating is delayed, consult distribution guidance for supported mitigations; none are specified in the supplied sources.

Validation and detection

  • Inventory running kernel versions and identify systems using the toshiba_acpi driver.
  • Confirm each kernel package includes the branch-appropriate stable fix or an equivalent vendor backport.
  • Reboot after updating and verify the running kernel is the remediated build.
  • Review distribution advisories because package versions may not directly match upstream kernel releases.
