Qualcomm Multiple Chipsets vulnerability
Multiple Qualcomm chipsets contain a use-after-free vulnerability in DSP Services memory management, enabling code execution through memory corruption.
Verdict
Today item — known-exploited.
A use-after-free flaw in Qualcomm chipset DSP Services allows attackers to corrupt memory and achieve code execution. Active exploitation in the wild increases risk despite low EPSS score.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
11 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 2024-10-08).
Probability (EPSS)
EPSS 0.00674 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) · Affected: Qualcomm, Multiple Chipsets . Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-416 Use After Free — 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.
Currency of the record
CISA added this to its KEV catalog 1 day after 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.
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 input that triggers improper memory deallocation in DSP Services HLOS memory map handling.
Business
Attackers gain arbitrary code execution on the device baseband processor, bypassing security controls.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the freed memory region to overwrite critical DSP data structures or inject executable code.
Business
Device integrity is compromised; attackers can intercept communications, persist malware, or escalate privileges to the application processor.
3
Lateral reach — past segmentation narrative 3
Attacker
I leverage baseband-level access to establish a persistent foothold independent of OS-level defenses.
Business
Remediation becomes difficult; standard patching and security updates may not fully restore device trustworthiness.
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.
