Linux Kernel Memory Leak Vulnerability in fbdev Component

CVE-2022-50404

What is CVE-2022-50404?

A memory leak vulnerability exists within the Linux kernel's fbdev component, specifically during the execution of the fbcon_do_set_font() function. This issue arises when the changes made by the vc_resize() function fail, leading to an allocated buffer not being released. Consequently, this oversight can result in a gradual increase in memory usage, potentially degrading system performance. It is crucial for users and system administrators to apply the necessary updates to mitigate this vulnerability and ensure optimal kernel performance.
