Linux Kernel vulnerability
Linux Kernel USB-audio driver contains an out-of-bounds read vulnerability allowing local privileged attackers to access sensitive information.
Verdict
Today item — known-exploited.
A local privilege-required out-of-bounds read in the USB-audio driver enables information disclosure. Active exploitation in the wild indicates practical attack feasibility, though ransomware deployment is not associated with this vulnerability.

Is it exploitable?
— the evidence, ranked above the scoreReported 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 2025-04-09).
Probability (EPSS)
EPSS 0.01351 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 7.1 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H) · Affected: Linux, Kernel. Confirm exact fixed builds in the vendor advisory.CVSS — CISA-assigned via the ADP container (CVE.org), version 3.1; the CNA left no metrics, so CISA's own score is used ahead of NVD.
Weakness (CWE)
Mapped to CWE-125 Out-of-bounds Read — weakness family: Memory safety.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: partialCISA'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 106 days 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.

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 gain local system access with elevated privileges to interact with USB-audio driver interfaces.
Business
Attackers with existing system compromise can escalate information gathering capabilities without additional privilege elevation.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I trigger an out-of-bounds read condition in the USB-audio driver to access kernel memory beyond intended boundaries.
Business
Sensitive kernel data, cryptographic material, or authentication tokens become exposed to privileged local processes.
3
Lateral reach — past segmentation narrative 3
Attacker
I extract confidential information from kernel memory to support lateral movement or persistence objectives.
Business
Information disclosure compounds security posture degradation and enables multi-stage attack chains targeting higher-value assets.
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.
