Description

This security bulletin contains information about 2 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2026-40144)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 7.3 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to execute arbitrary code in kernel mode.

The vulnerability exists due to out-of-bounds read in a kernel-mode component when processing input. A local user can trigger memory corruption to execute arbitrary code in kernel mode.

Exploitation requires local access to the endpoint.


2) Insufficient Granularity of Access Control (CVE-ID: CVE-2026-40145)

CWE-ID: CWE-1220 - Insufficient Granularity of Access Control

CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local privileged user to bypass the product's anti-tamper protection.

The vulnerability exists due to insufficient granularity of access control in the interaction between a support utility and the agent's tamper protection controls when the utility process protections are not enforced as intended. A local privileged user can influence the support utility process to bypass the product's anti-tamper protection.

Exploitation requires local access, an existing elevated process context, and additional preconditions on the endpoint.
