CVE-2026-74676

Опубликовано: 22 авг. 2026

CVSS3: 5.5

Описание

In the Linux kernel, the following vulnerability has been resolved: vt: add permission check for KDSKBMETA ioctl KDSKBMETA modifies keyboard meta mode but lacks the !perm check that all other keyboard setter ioctls in vt_k_ioctl() enforce, allowing a process to change meta mode on a non-controlling console without authorization.

A flaw was found in the Linux kernel. A missing permission check in the KDSKBMETA ioctl (input/output control) allows a local process to modify the keyboard meta mode on a non-controlling console without proper authorization. This could enable an attacker to make unauthorized changes to system keyboard settings.
