Qualcomm Multiple Chipsets vulnerability

Multiple Qualcomm chipsets contain a use of out-of-range pointer offset vulnerability in Graphics processing when handling large sync point lists via IOCTL_KGSL_GPU_AUX_COMMAND, enabling memory corruption.

Verdict

Today item — known-exploited.

A memory corruption flaw in Qualcomm chipset graphics drivers allows attackers to exploit out-of-range pointer offsets through crafted GPU auxiliary commands, potentially enabling code execution or system compromise.

Weakness (CWE)
Mapped to CWE-823 CWE-823 — weakness family: Memory safety.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.

CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
CISA-ADP ↗Reported
Currency of the record
CISA added this to its KEV catalog the same day the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

Who’s exploiting it?

— attribution turns risk into urgency
Attribution not established

No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.

Why it matters

— the attack path, told twice: adversary, then board
1

Front door — unauthenticated access narrative 1

Attacker
I craft a malicious GPU auxiliary command with an oversized sync point list to trigger an out-of-range pointer offset in the graphics driver.
Business
Unpatched devices become vulnerable to local privilege escalation or arbitrary code execution within the GPU context.
2

Keys to the kingdom — privilege/identity takeover narrative 2

Attacker
I exploit the memory corruption to read or write sensitive kernel memory regions accessible through the graphics subsystem.
Business
Attackers gain ability to bypass security boundaries and escalate privileges to kernel level on affected Qualcomm-based devices.
3

Lateral reach — past segmentation narrative 3

Attacker
I leverage the vulnerability to achieve persistent code execution or establish a foothold for further system compromise.
Business
Device integrity is compromised, enabling malware installation, data theft, or lateral movement within enterprise environments.

What to do

— defensible action
  • Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
