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.

Linux kernel slab out-of-bounds read vulnerability

The Linux kernel is a computer operating system kernel written in C and assembly language, compliant with the POSIX standard, and distributed under the GNU General Public License. A slab out-of-bounds read vulnerability exists in fbcon in Linux kernel versions prior to 5.9.7. The vulnerability...

CVE-2020-28974

CVE-2020-28974 is a slab-out-of-bounds read in the Linux kernel’s fbcon driver, fixed in kernel 5.9.7. The flaw arises in KD_FONT_OP_COPY within drivers/tty/vt/vt.c and could allow a local attacker to read privileged kernel memory or cause a kernel crash. Several connected documents describe the ...

A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest under specific conditions can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.
