Known Exploited Vulnerability

This Linux Kernel Use of Uninitialized Resource Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. The Linux kernel contains a use of uninitialized resource vulnerability that allows an attacker to leak kernel memory via a specially crafted HID report.

The following remediation steps are recommended / required by March 25, 2025: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Vulnerability Analysis

CVE-2024-50302 is exploitable with local system access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. It has an exploitability score of 1.8 out of four. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.

Use of Uninitialized Resource

The software uses or accesses a resource that has not been initialized. When a resource has not been properly initialized, the software may behave unexpectedly. This may lead to a crash or invalid memory access, but the consequences vary depending on the type of resource and how it is used within the software.
