It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef (\\\"ovl: stack file ops\\\"). This was fixed in kernel version 5.8 by commits 56230d9 (\\\"ovl: verify permissions in ovl_path_open()\\\"), 48bd024 (\\\"ovl: switch to mounter creds in readdir\\\") and 05acefb (\\\"ovl: check permission to open real file\\\"). Additionally, commits 130fdbc (\\\"ovl: pass correct flags for opening real directory\\\") and 292f902 (\\\"ovl: call secutiry hook in ovl_real_ioctl()\\\") in kernel 5.8 might also be desired or necessary. These additional commits introduced a regression in overlay mounts within user namespaces which prevented access to files with ownership outside of the user namespace. This regression was mitigated by subsequent commit b6650da (\\\"ovl: do not fail because of O_NOATIMEi\\\") in kernel 5.11.\"},{\"lang\":\"es\",\"value\":\"Overlayfs no realizaba apropiadamente la
