Qualcomm Multiple Chipsets vulnerability
Multiple Qualcomm chipsets contain an integer overflow vulnerability in Graphics Linux during shared virtual memory region assignment via IOCTL calls, enabling memory corruption.
Verdict
Today item — known-exploited.
Integer overflow in memory handling allows local attackers to corrupt kernel memory and potentially escalate privileges or cause denial of service on affected Qualcomm chipset-based devices.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
5 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 0.00892 — 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-190 Integer Overflow — 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
Gain local code execution access to a device running affected Qualcomm chipsets.
Business
Device compromise enables unauthorized access to sensitive data and system functions.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
Trigger integer overflow during IOCTL shared virtual memory assignment to corrupt kernel memory structures.
Business
Memory corruption destabilizes system integrity and creates exploitation pathways for privilege escalation.
3
Lateral reach — past segmentation narrative 3
Attacker
Escalate privileges from user-level to kernel-level access through corrupted memory state.
Business
Full system compromise allows attacker to bypass security controls and maintain persistent access.
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.
