01

What, why and how

Out-of-bounds read in Microsoft Office allows an unauthorized attacker to disclose information locally.

What

Out-of-bounds read in Microsoft Office allows an unauthorized attacker to disclose information locally.

Why

The product reads data past the end, or before the beginning, of the intended buffer.

How

An attacker operating through local access may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

02

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 → Out-of-bounds Read → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Local
Privileges required
None: unauthenticated exploitation is possible
User interaction
Required interaction required
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-125 ↗

CWE-125: Out-of-bounds Read. The product reads 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:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C

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.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.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-2026-0237Kwetsbaarheden verholpen in Microsoft Office

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot categorieën schade, zoals benoemd in onderstaande tabel. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide bestand te openen of link te volgen, met uitzondering van SharePoint. Voor succesvol misbruik van kwetsbaarheden in SharePoint is geen gebruikersinteractie nodig, anders dan het volgen van een malafide link. Microsoft heeft in een update bevestigd dat SharePoint kwetsbaarheid CVE-2026-58644 actief als zeroday is misbruikt. Het NCSC raadt aan kwetsbare SharePoint systemen zo snel mogelijk te updaten naar de nieuwste versie om misbruik te voorkomen. De kwetsbaarheid CVE-2026-58644 betreft een deserialization-kwetsbaarheid welke misbruik zou kunnen worden om op afstand code uit te voeren. Mogelijk is de kwetsbaarheid CVE-2026-58644 in combinatie met SharePoint-kwetsbaarheid CVE-2026-56164 door kwaadwillende te misbruiken om zonder authenticatie op afstand code uit te voeren. De kwetsbaarheid CVE-2026-56164 betreft een privilegeescalation-kwetsbaarheid, deze zou misbruikt kunnen worden om rechten binnen een netwerk te verhogen. UPDATE: Volgens watchTowr is er een publieke exploit code voor SharePoint kwetsbaarheid CVE-2026-50522 gepubliceerd en wordt deze op on-premise versies van SharePoint nu ook actief misbruikt. Kwaadwillenden kunnen deze kwetsbaarheid misbruiken om zichzelf voor langere termijn toegang tot netwerken van kwetsbare systemen te verschaffen, door middel van het stelen van machine-keys. ```
