NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-vanilla-base package and not the kernel-vanilla-base package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.
