Background
The Linux Kernel is the core component of the Linux operating system, responsible for managing system resources and providing essential services. It is a widely used open-source package that powers numerous devices, servers, and embedded systems. The vulnerability identified in this report pertains to the 'trusted' subsystem of the Linux Kernel, specifically related to a memory leak issue on the object td.
Vulnerability Detail
The memory leak vulnerability in the 'trusted' subsystem of the Linux Kernel allows an attacker to exploit a flaw in the handling of object td, leading to a gradual depletion of system memory. This can result in reduced performance, system instability, and potential denial-of-service (DoS) conditions. The vulnerability was introduced in version v5.12 of the Linux Kernel and was fixed in version v5.12.5.
How To Fix
No fixed version is published for this vulnerability.
