In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: avoid NULL pointer dereference
When iterating over the links of a vif, we need to make sure that the
pointer is valid (in other words - that the link exists) before
dereferncing it.
Use for_each_vif_active_link that also does the check.
Security readout for executives and security teams
Plain-English summary
CVE-2024-58062 is a Linux kernel flaw in the iwlwifi MVM Wi-Fi driver. A local, low-privileged user could trigger a NULL pointer dereference and cause a denial of service. The sources show no evidence of active exploitation or data theft impact.
Executive priority
Treat this as a routine-to-prioritized kernel availability fix, not an emergency. Raise priority for managed laptops, workstations, or systems where a local denial of service would disrupt operations. There is no sourced evidence of active exploitation.
Technical view
The bug is CWE-476 in Linux iwlwifi MVM link iteration. The kernel code could dereference a missing vif link before checking it exists. The resolved change uses for_each_vif_active_link to validate active links before dereference. CVSS 3.1 is 5.5: local, low complexity, low privileges, availability impact only.
Likely exposure
Exposure appears limited to Linux systems running affected kernel versions with the iwlwifi MVM Wi-Fi driver path present. The CVE record identifies Linux kernel versions including 6.12, 6.12.13, 6.13.2, and 6.14 as affected, but distribution backport status is not provided.
Exploitation context
The CVSS vector indicates local access with low privileges is required, no user interaction is needed, and the expected impact is high availability loss. The source bundle says KEV is false and provides no cited evidence of exploitation in the wild.
Researcher notes
The key issue is a missing validity check while iterating vif links in iwlwifi MVM. The fix direction is explicit in the kernel description: use for_each_vif_active_link, which checks that the link exists before dereferencing. No exploit mechanics are provided by the sources.
Mitigation direction
Update to a kernel package containing the referenced stable fixes.
Check Linux distribution advisories for backported fixes before relying on version strings.
Prioritize endpoints using affected wireless hardware and iwlwifi MVM.
Apply normal kernel reboot procedures after updating.
Monitor vendor guidance for additional affected-version clarification.
Validation and detection
Inventory Linux kernel versions across wireless-capable endpoints.
Confirm whether iwlwifi MVM is present on in-scope systems.
Verify installed kernels include the referenced stable fix commits or vendor backports.
Review crash telemetry for iwlwifi NULL pointer dereference patterns.
Document any systems deferred from kernel updates.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

NULL Pointer Dereference
NULL Pointer Dereference represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
