CVEs this fix closes
| Priority | CVE | Title | Impact | CVSS | EPSS | Exploitation |
|---|---|---|---|---|---|---|
| High | CVE-2026-86145 | PCRE2 before 10.48 allows a pcre2_dfa_match 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 regular expression, or a recursive pattern in conjunction with a small heap limit (this can be set through the API). | 8.2 | 0.0043 | None reported | |
| High | CVE-2026-103111 | PCRE2 before 10.49, when there is an attacker-controlled regular expression and certain JIT API usage, allows an out-of-bounds write with arbitrary data. | 8.2 | 0.0027 | None reported | |
| High | CVE-2026-89161 | In PCRE2 before 10.48, pcre2_jit_match mishandles a previously copied subject being passed in as a context. An incorrect free operation can occur. | 8.2 | 0.0013 | None reported |
