AI-suggested
An official patch is available and should be applied to affected Linux kernel versions to resolve the memory leak. Users should update their systems to the fixed kernel versions as provided by their Linux distribution vendors. No additional mitigation actions are required beyond applying the official fix.
Description
A memory leak vulnerability in the Linux kernel's uvesafb framebuffer driver was fixed. The issue was caused by an incorrect goto label in the uvesafb_probe() function, which prevented allocated memory for modedb and modelist in uvesafb_vbe_init() from being freed on some error paths. This flaw could lead to resource exhaustion over time. The vulnerability affects specific Linux kernel versions and has been addressed by an official patch.
