01

What, why and how

Apple iOS, iPadOS, macOS, tvOS, and watchOS RTKit contain a memory corruption vulnerability that allows an attacker with arbitrary kernel read and write capability to bypass kernel memory protections.

What

Apple iOS, iPadOS, macOS, tvOS, and watchOS RTKit contain a memory corruption vulnerability that allows an attacker with arbitrary kernel read and write capability to bypass kernel memory protections.

Why

A bounds error lets data be written beyond the intended memory region, potentially corrupting control data.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2024-03-06.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Out-of-bounds Write → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Local
Privileges required
Low: a basic authenticated account is required
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-787 ↗

CWE-787: Out-of-bounds Write. The product writes data past the end, or before the beginning, of the intended buffer.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.

NCSC-NL · Dutch · NCSC-2024-0320Kwetsbaarheden verholpen in Apple MacOS

Een kwaadwillende kan de kwetsbaarheden misbruiken om een beveiligingsmaatregel te omzeilen, zichzelf verhoogde rechten toe te kennen, toegang te krijgen tot gevoelige gegevens, willekeurige code uit te voeren, mogelijk met kernel-rechten of een Denial-of-Service te veroorzaken. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide app te installeren en draaien, of een malafide link te volgen. Voor het uitvoeren van willekeurige code met kernel-rechten moet de kwaadwillende reeds beschikken over verhoogde rechten op het kwetsbare systeem.
