Several methods in sized-chunks drop elements before updating the length/boundary metadata. If an element's Drop panics during the drop, the metadata update is skipped, so the container still treats the already-dropped elements as live. When the container's own Drop runs, those elements are visit...

CVE-2026-65066

Data::RingBuffer::Shared versions before 0.04 for Perl create a world-readable mmap backing file and open it without OEXCL or ONOFOLLOW. The segment is created in ring.h with openpath, ORDWR|OCREAT, 0666. The mode is 0666, so under the default umask 022 the file is created mode 0644 world-readabl...

CVE-2026-65066

Data::RingBuffer::Shared for Perl versions prior to 0.04 are vulnerable to local information disclosure and race conditions. The issue stems from the creation of an mmap backing file in ring.h using open(path, O_RDWR|O_CREAT, 0666). Because the O_NOFOLLOW flag is missing, the system follows pre-p...
