- Details
-
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 KDFONTOP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height.
