CVE-2022-50159

CVE-2022-50159 concerns the Linux kernel: the function that restores ima-kexec-buffer may read outside the addressable RAM if the previous kernel’s buffer lies beyond the new kernel’s memory map, risking kernel panic when booting with mem=X. A fix was implemented to validate the returned PFN rang...
