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