In the Linux kernel, the following vulnerability has been resolved: ovl: check access to copy_file_range source with src mounter creds Commit… (CVE-2026-68448)CVE-2026-68448 0 A vulnerability in the Linux kernel overlayfs implementation related to the copy_file_range operation has been resolved. The issue involved incorrect credential checks when copying files across overlayfs filesystems, potentially allowing read access to files that should be denied or denying access that should be allowed. The fix ensures that read access to the source file is verified using the correct mounter credentials. This vulnerability affects the overlayfs filesystem's handling of cross-submount copy operations. Join the discussion | GCVE Database | 08/12/2026, 03:31:16 UTC Added: 08/12/2026, 16:12:24 UTC |
