01

What, why and how

In DevmemIntPFNotify of devicemem_server.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.

What

In DevmemIntPFNotify of devicemem_server.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.

Why

The program can continue using memory after it has been released, producing unsafe and attacker-influenceable behaviour.

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.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

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 → Use After Free → 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
High: exploitation depends on specific conditions
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-416 ↗

CWE-416: Use After Free. The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory belongs to the code that operates on the new pointer.

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:H/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.ACHighAttack complexity: Successful exploitation depends on specific conditions outside the attacker's direct control.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-2024-0358Kwetsbaarheden verholpen in Google Android en Samsung Mobile

Een kwaadwillende kan de kwetsbaarheden misbruiken om zich verhoogde rechten toe te kennen op het device en zo willekeurige code uit te voeren, mogelijk met rechten van het systeem en toegang krijgen tot gevoelige gegevens. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide app te installeren en draaien of een malafide link te volgen. In deze update wordt ook de kwetsbaarheid met kenmerk CVE-2024-32896 verholpen. Deze bevindt zich in het Android Framework en stelt een lokale kwaadwillende in staat om zich verhoogde rechten toe te kennen en code uit te voeren met rechten van het systeem. Van deze kwetsbaarheid meldt Google dat deze zeer beperkt en gericht is misbruikt als ZeroDay op Google Pixel. Er is (nog) geen publieke Proof-of-Concept of exploit beschikbaar. In deze update zijn ook kwetsbaarheden verholpen in closed-source componenten van Arm, Imagination Technologies, Unisoc en Qualcomm. Google heeft verder weinig inhoudelijke informatie bekend gesteld.
