CVE-2026-74676

CVE-2026-74676 affects the Linux kernel virtual terminal (VT) subsystem. The KDSKBMETA ioctl, which modifies keyboard meta mode, lacked the !perm permission check enforced by all other keyboard setter ioctls in vt_k_ioctl() . This allowed a process to change the meta mode on a non-controlling con...

CVE-2026-74675

A race condition in the Linux kernel's virtual terminal (vt) subsystem affects the kbd_keycode() function, which reads vc->port.tty without acquiring a proper tty reference. This races against con_shutdown(), which clears port.tty under a different lock, potentially leading to a use-after-free...
