CVE-2026-46065

CVE-2026-46065 affects the Linux kernel framebuffer (fbdev) defio mechanism. The issue arises from disconnecting deferred I/O from the lifetime of struct fb_info, by holding state in struct fb_deferred_io_state and freeing the instance only after the final mapping closes. If fb_info/defio are fre...
