Why It Matters

A local non-privileged user can make improper GPU memory processing operations to gain access to already freed memory.

SOC priority

Immediate Attention

Actively exploited (source statement)

Yes

Publicly disclosed

Unknown

Risk basis: CISA KEV exploitation signal; Known exploitation signal from CISA KEV or ransomware metadata; Source-confirmed exploitation or CISA KEV/ransomware metadata

Vendor or catalog guidance (source)

  • CISA KEV: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

Known exploitation (source facts)

Only what a source states. Unknown means no source has said either way; it is not "not exploited".

Suggested hunting (rule-based inference)

SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.

Matched local-access-review (CVSS AV:L, CVSS PR:L)

Exposure

  1. Identify hosts reporting this CVE, prioritising shared or multi-user systems.Telemetry: DeviceTvmSoftwareVulnerabilities · A local, low-privilege vector matters most where untrusted users can run code. · Rule local-access-review

Exploitation evidence

  1. Review source-stated impact and relevant application errors on affected hosts; local access alone does not establish privilege escalation.Telemetry: DeviceProcessEvents · The vector establishes local access and low privileges only. Confirm the impact from the advisory before choosing a specific hunt. · Rule local-access-review

Response

  1. Confirm the source-stated update on affected hosts.Telemetry: DeviceTvmSoftwareVulnerabilities · Host inventory can verify remediation. · Rule local-access-review
