CVE-2026-86145

PCRE2 before 10.48 allows a pcre2dfamatch out-of-bounds write because reuse of a cached workspace block, in a recursive DFA matching workspace, lacks a size check even though a newly allocated block, for the same purpose, does have a size check. This outcome requires an attacker-controlled regula...
