#Security Vulnerability

**What is the version information for this release?** Microsoft Edge Version Date Released Based on Chromium Version 142.0.3595.80 11/13/2025 142.0.7444.162/.163

Missing authorization in Nuance PowerScribe allows an unauthorized attacker to disclose information over a network.

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

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

Heap-based buffer overflow in Microsoft Graphics Component allows an unauthorized attacker to execute code over a network.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** In this case, a successful attack could be performed from a low privilege Hyper-V guest. The attacker could traverse the guest's security boundary to cause denial of service on the Hyper-V host environment.

Buffer over-read in Windows TDX.sys allows an authorized attacker to elevate privileges locally.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** With successful exploitation of this vulnerability, an attacker could gain elevated privileges equivalent to a system managed administrator, allowing them to execute arbitrary code with high integrity and bypass administrator protections.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to execute code over a network.
