Description
A flaw was found in Linux Kernel because access to the global variable fg_console is not properly synchronized leading to a use after free in con_font_op.
A use-after-free flaw was found in the Linux kernel’s TTY driver functionality in the way the user triggers the con_font_op function. This flaw allows a local user to crash or escalate their privileges on the system or expose sensitive information (kernel memory).
