Background
The thermal: int340x is a component of the Linux Kernel that handles thermal management for Intel processors. It provides support for various Intel-specific thermal features and notifications. The vulnerability in the int340x component can lead to a memory leak, causing the system to exhaust available memory resources over time.
Vulnerability Detail
The vulnerability in the int340x component of the Linux Kernel allows an attacker to trigger a memory leak by exploiting a flaw in the int3400_notify() function. By repeatedly invoking this function without proper memory deallocation, an attacker can cause the system to gradually consume more memory, potentially leading to a denial-of-service condition or other adverse effects. The vulnerability was introduced in version v4.14 of the Linux Kernel and has been fixed in version v5.10.103.
How To Fix
No fixed version is published for this vulnerability.
