  "details": "PCRE2 before 10.48 allows a pcre2_dfa_match out-of-bounds write because\nreuse of a cached workspace block, in a recursive DFA matching\nworkspace, lacks a size check (even though a newly allocated block, for\nthe same purpose, does have a size check). This outcome requires an\nattacker-controlled regular expression, or a recursive pattern in\nconjunction with a small heap limit (this can be set through the API).\n(CVE-2026-86145)\nPCRE2: out-of-bounds write in JIT matching with large stack allocations.\n(CVE-2026-103111)\n",
