CVE-2026-63826 fbdev: fix use-after-free in store_modes()

In the Linux kernel, the following vulnerability has been resolved: fbdev: fix use-after-free in storemodes storemodes replaces a framebuffer's modelist with modes from userspace. On success it frees the old modelist with fbdestroymodelist. Two fields still point into that freed list. One pointer...

CVE-2026-53402

The CVE-2026-53402 issue affects the Linux kernel’s fbdev/fbcon path. When fbcon_do_set_font() fails (e.g., vc_resize() under memory pressure), the error path (err_out) only rolls back vc_font.charcount and neglects to restore hi_font state and the screen buffer. This leaves vc_hi_font_mask set, ...
