Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.18% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Linux Linux and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 252 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Distribution package intelligence

Release-specific package status

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

25 package states
Package result overrides the generic status

BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 20 affected package states shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.

Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Summary
A flaw was found in the `drm/amdkfd` component of the Linux kernel. A race condition exists in the `kfd_criu_checkpoint_events()` function where a mutex is not consistently held during event checkpointing. This allows a local attacker to cause memory corruption, potentially leading to privilege escalation or a denial of service (DoS).
Remediation
To mitigate this vulnerability, prevent the amdgpu kernel module from loading on systems where AMD GPU compute or display hardware is not required. 1. Blacklist the module by executing the following command as root: # echo "install amdgpu /bin/true" > /etc/modprobe.d/disable-amdgpu.conf 2. If the module is currently loaded into kernel memory, a system reboot is required to fully unload it, or attempt to unload it manually: # rmmod amdgpu Warning: Unloading the kernel module or rebooting the host will interrupt running services and terminate graphical sessions. Caveat: Disabling the amdgpu driver prevents hardware graphics acceleration and compute functionality on systems equipped with AMD Radeon or Instinct GPUs. Ensure alternative console access is available.

No EUVD known-exploited evidence

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: hold event_mutex while checkpointing CRIU events kfd_criu_checkpoint_events() counts the entries in p->event_idr via kfd_get_num_events(), allocates an array sized to that count, and then walks the same IDR to fill it. Neither the count nor the walk holds p->event_mutex. The CRIU checkpoint caller holds only p->mutex. Event create and destroy (kfd_event_create()/kfd_event_destroy()) take p->event_mutex and do not take p->mutex, so a second thread in the same process can insert or remove events between the count and the walk. If an event is inserted, the walk iterates more entries than were counted and writes past the end of the ev_privs allocation; if an event is removed, the walk dereferences an entry that is being freed. Hold p->event_mutex across the count and the walk so both observe a consistent view of p->event_idr. The lock is released before copy_to_user(), which only touches the local buffer. The caller already holds p->mutex and the create/destroy paths never take p->mutex, so the p->mutex -> p->event_mutex order is not inverted and no deadlock is introduced. (cherry picked from commit ff57e223ab105795b05d3ef3f3c35a5a441bcbaa)

What, why and how

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: hold event_mutex while checkpointing CRIU events kfd_criu_checkpoint_events() counts the entries in p->event_idr via kfd_get_num_events(), allocates an array sized to that count, and then walks the same IDR to fill it. Neither the count nor the walk holds p->event_mutex. The CRIU checkpoint caller holds only p->mutex. Event create and destroy (kfd_event_create()/kfd_event_destroy()) take p->event_mutex and do not take p->mutex, so a second thread in the same process can insert or remove events between the count and the walk.

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

To mitigate this vulnerability, prevent the amdgpu kernel module from loading on systems where AMD GPU compute or display hardware is not required. 1. Blacklist the module by executing the following command as root: # echo "install amdgpu /bin/true" > /etc/modprobe.d/disable-amdgpu.conf 2. If the module is currently loaded into kernel memory, a system reboot is required to fully unload it, or attempt to unload it manually: # rmmod amdgpu Warning: Unloading the kernel module or rebooting the host will interrupt running services and terminate graphical sessions. Caveat: Disabling the amdgpu driver prevents hardware graphics acceleration and compute functionality on systems equipped with AMD Radeon or Instinct GPUs. Ensure alternative console access is available.
