CVE-2026-64615

CVE-2026-64615 affects Data::Graph::Shared for Perl, specifically versions before 0.04. The implementation creates a world-readable mmap backing file by opening path with O_RDWR|O_CREAT and mode 0666 (leading to 0644 under default umask), without O_NOFOLLOW or O_EXCL checks. This enables local us...

CVE-2026-64615

CVE-2026-64613 Data::Buffer::Shared versions before 0.05 for Perl create a world-readable mmap backing file and open it without O_NOFOLLOW

Data::Buffer::Shared versions before 0.05 for Perl create a world-readable mmap backing file and open it without ONOFOLLOW. The segment is created in bufgeneric.h with openpath, ORDWR|OCREAT|OEXCL, 0666. OEXCL blocks a pre-seeded file on create, but the mode is 0666, so under the default umask 02...

CVE-2026-64613
