Type Values Removed Values Added
Description In the Linux kernel, the following vulnerability has been resolved: xen: unexport __init-annotated xen_xlate_map_ballooned_pages() EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic. modpost used to detect it, but it has been broken for a decade. Recently, I fixed modpost so it started to warn it again, then this showed up in linux-next builds. There are two ways to fix it: - Remove __init - Remove EXPORT_SYMBOL I chose the latter for this case because none of the in-tree call-sites (arch/arm/xen/enlighten.c, arch/x86/xen/grant-table.c) is compiled as modular. This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
