Apple macOS vulnerability
macOS Monterey contains an out-of-bounds read vulnerability allowing applications to read kernel memory. The flaw has been exploited in the wild.
Verdict
Today item — known-exploited.
An attacker can exploit this out-of-bounds read to access sensitive kernel memory from a local application context, potentially disclosing system secrets or enabling privilege escalation chains.

01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
3 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 2022-04-04).
Probability (EPSS)
EPSS 0.01133 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) · Affected: Apple, macOS. 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-20 Improper Input Validation, 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 the same day 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 craft a malicious application that triggers an out-of-bounds read in macOS kernel memory handling.
Business
User systems face information disclosure risk if kernel memory contents are leaked to unauthorized processes.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I extract sensitive kernel data such as addresses, credentials, or cryptographic material through repeated memory reads.
Business
Confidentiality of system-level secrets is compromised, undermining security guarantees of the operating system.
3
Lateral reach — past segmentation narrative 3
Attacker
I use disclosed kernel information to bypass address space layout randomization or other memory protections in follow-up exploits.
Business
Attack surface expands for privilege escalation or persistent compromise of affected macOS devices.
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.
