Last modified
CVE-2026-116732 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. libdwarf through 2.3.3 contains a heap out-of-bounds read vulnerability in dwarf_debug_addr_table() that omits the table starting offset when validating .debug_addr unit length. Attackers can supply a crafted object file with a non-zero offset table, causing dwarf_debug_addr_by_index() to read past the heap buffer, disclosing adjacent heap bytes or crashing consumers.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
