Including for\nthreads that no longer have a VM (and maybe never did, like most kernel\nthreads).\n\nIt's not what this flag was designed for, but it is what it is.\n\nThe ptrace code does check that the uid/gid matches, so you do have to\nbe uid-0 to see kernel thread details, but this means that the\ntraditional \"drop capabilities\" model doesn't make any difference for\nthis all.\n\nMake it all make a *bit* more sense by saying that if you don't have a\nMM pointer, we'll use a cached \"last dumpability\" flag if the thread\never had a MM (it will be zero for kernel threads since it is never\nset), and require a proper CAP_SYS_PTRACE capability to override."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
