CVE-2026-59145: EGOR Data::Intern::Shared out-of-bounds read in si_idx_find

CVE-2026-59145 · Severity: info · CVSS 0 · Published 2026-07-21

Data::Intern::Shared is a Perl module used for sharing string data between different processes. A security flaw allows a local user who can modify the shared data file to trigger an out-of-bounds memory read. This could allow an attacker to access sensitive information from the memory of other programs using the same shared data.

Vendors: EGOR Data.

Technical details

An out-of-bounds read vulnerability exists in the si_idx_find function of Data::Intern::Shared due to insufficient validation of indices within mmap'd segments. While si_validate_header checks basic layout parameters, it fails to validate the slot, reverse, and arena arrays. A local attacker with write access to the backing file can poison these indices to cause triple indirection dereferences outside of the allocated memory bounds. This can be exploited via id_of, intern, or string lookups to disclose adjacent process memory. The issue is addressed in version 0.02.
