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 0.01132 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Apple, macOS. Confirm exact fixed builds in the vendor advisory.
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; 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 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.
