In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
bpf: Add missing access_ok call to copy_user_syms<\/p>\n
As reported by sashiko we use __get_user without prior access_ok call on the
\nuser space pointer. Adding the missing call for the whole pointer array.<\/p>\n
Plus removing the err check in the error path, because it’s not needed and
\nalso we can return -ENOMEM directly from the first kvmalloc_array fail path.<\/p>\n
