#vulnerability

Use after free in Windows Common Log File System Driver allows an authorized attacker to elevate privileges locally.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

Heap-based buffer overflow in Windows Win32K - GRFX allows an unauthorized attacker to execute code locally.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of certain kernel memory content.

Out-of-bounds read in Windows NTFS allows an unauthorized attacker to elevate privileges locally.

Deserialization of untrusted data in Microsoft Office SharePoint allows an unauthorized attacker to execute code 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. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to a high loss of confidentiality (C:H), and some loss of integrity (I:L) and no loss of availability (A:N). What does that mean for this vulnerability?** An attacker who successfully exploited this vulnerability could view sensitive information, a token in this scenario (Confidentiality), and make some changes to disclosed information (Integrity), but they would not be able to affect Availability.

Heap-based buffer overflow in Windows Common Log File System Driver allows an authorized attacker to elevate privileges locally.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of certain memory address within kernel space. Knowing the exact location of kernel memory could be potentially leveraged by an attacker for other malicious activities.
