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.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
4 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 0.01254 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Linux, Kernel. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-125 Out-of-bounds Read — 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 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.
