CVE-2022-49419

The CVE-2022-49419 issue affects the Linux kernel vesafb (video: fbdev) where use-after-free can occur if the fb_info is freed in the .remove path before or after .fb_destroy. The underlying cause is an ordering bug: the code previously freed fb_info in .remove, which could reference freed memory...
