CVE-2024-50302

Description

A vulnerability was found in the Linux kernel's driver for Human Interface Devices. This flaw allows an attacker to use a malicious input device to read information from the report buffer. This could be used to leak kernel memory, enabling the exploitation of additional vulnerabilities.

Statement

While this vulnerability could lead to disclosure of kernel memory, the impact is rated Moderate because exploitation requires bypassing additional security features such as kernel address-space layout randomization (KASLR). It could be exploited by an authenticated, local attacker who emulates a malicious Human Interface Device (HID).

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Memory; Read Application Data

When reusing a resource such as memory or a program variable, the original contents of that resource may not be cleared before it is sent to an untrusted party.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

The uninitialized resource may contain values that cause program flow to change in ways that the programmer did not intend.
