Apple Multiple Products vulnerability
Apple's iOS, macOS, tvOS, watchOS, and visionOS contain a buffer overflow vulnerability allowing arbitrary code execution for attackers with memory write capability.
Verdict
Today item — known-exploited.
A memory buffer bounds violation in multiple Apple platforms enables code execution when an attacker gains write access to memory. Active exploitation in the wild increases risk despite low EPSS score.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
11 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 2026-02-12).
Probability (EPSS)
EPSS 0.01319 — 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-119 Memory Buffer Bounds Error — 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 initial memory write access through a separate vulnerability or misconfiguration.
Business
Attackers establish a foothold for privilege escalation or lateral movement within the organization's Apple device fleet.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft malicious data that overflows the buffer to corrupt adjacent memory and redirect execution flow.
Business
Arbitrary code runs with the privileges of the vulnerable process, potentially compromising sensitive data or system integrity.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary code to install persistence mechanisms or exfiltrate credentials and intellectual property.
Business
Long-term compromise of endpoints enables data theft, espionage, or supply chain attacks affecting customers and partners.
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.
