Last modified
CVE-2026-111140 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. libregf through 20260526 contains a heap out-of-bounds read in libregf_value_item_read_value_data() because it bounds value data size without subtracting the 4-byte old-format cell offset. Attackers can supply a crafted version 1.0/1.1 REGF hive with a value data cell ending its hive bin to leak adjacent heap bytes or crash parsers like regfexport and plaso.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
