NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel-azure package and not the kernel-devel-azure package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

A slab-out-of-bounds read in fbcon in the Linux kernel before 5.9.7 could be used by local attackers to read privileged information or potentially crash the kernel, aka CID-3c4e0dff2095. This occurs because KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height.
