CVE-2026-64245

A flaw was found in the Linux kernel's framebuffer device fbdev subsystem. Specifically, within the fbfindmode function, a use-after-free UAF vulnerability exists. This occurs because a memory buffer is released while still being referenced, potentially allowing an attacker to access or manipulat...

CVE-2026-63826

A flaw was found in the Linux kernel's framebuffer device fbdev component. When the storemodes function replaces a framebuffer's list of display modes, it fails to properly clear old pointers before freeing the old list. This can result in a use-after-free vulnerability, a type of memory...

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, ...
