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.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
6 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2023-12-05).
Probability (EPSS)
EPSS 0.00854 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Qualcomm, Multiple Chipsets. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-823 CWE-823 — weakness family: Memory safety.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution 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.
03
Why it matters
— the attack path, told twice: adversary, then board1
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.
04
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.
