Background
The Kernel is a crucial component of the Linux operating system that manages system resources and facilitates communication between hardware and software. It provides essential functionalities such as process management, memory management, and device drivers. The ice_add_adv_recipe() function in the Kernel's ice module is responsible for adding an advanced recipe to the switch. This recipe defines how packets should be processed by the switch. However, a vulnerability has been discovered in this function that can lead to a memory leak.
Vulnerability Detail
The vulnerability in ice_add_adv_recipe() can result in a memory leak, which occurs when memory is allocated but not properly deallocated. This can lead to a gradual depletion of available memory resources, potentially causing system instability or denial of service. The vulnerability was introduced in version v5.16 of the Linux Kernel and was fixed in version v6.1.12. The impact and attack plausibility of this vulnerability have not been proven yet.
