CVE-2023-52973

The CVE-2023-52973 issue affects the Linux kernel’s vc_screen path (vt/vc_screen.c). Root cause: a use-after-free of vc_data after console_unlock() in vcs_read(), where the vc_data pointer was loaded inside the loop, allowing a UAF in vcs_size(). The bug was fixed by moving the vc_data load to th...
