Apple Multiple Products vulnerability
Apple's iOS, iPadOS, macOS, tvOS, and watchOS contain a TOCTOU vulnerability in memory handling that allows attackers with read/write access to bypass Pointer Authentication protections.
Verdict
Today item — known-exploited.
A time-of-check/time-of-use flaw in Apple operating systems enables privilege escalation or code execution for local attackers who can manipulate memory between validation and use, circumventing pointer integrity checks.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
2 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 2024-01-31).
Probability (EPSS)
EPSS 0.00487 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Apple, Multiple Products. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-367 TOCTOU Race Condition.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 initial read and write access to process memory through a separate vulnerability or local execution context.
Business
An attacker establishes a foothold for further exploitation within the device.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I identify the window between pointer validation and pointer dereference, then modify the pointer value during that gap.
Business
Pointer Authentication, a critical exploit mitigation, is rendered ineffective.
3
Lateral reach — past segmentation narrative 3
Attacker
I redirect execution to arbitrary code by corrupting memory through the TOCTOU race condition.
Business
The device experiences unauthorized code execution with elevated privileges, compromising confidentiality and integrity.
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.
