CVE-2026-65067

CVE-2026-65067 affects Data::Intern::Shared prior to 0.02 for Perl. The code creates a world-readable mmap backing file via open(path, O_RDWR|O_CREAT, 0666) with mode 0666, which becomes 0644 under the default umask. Absence of O_NOFOLLOW means a symlink at the path is followed, and absence of O_...
