## CVEs this fix closes

| CVE | Priority | Title | CVSS | EPSS | Exploitation |
|---|---|---|---:|---:|---|
| [CVE-2026-86145](https://patchblox.com/security/data/cve/CVE-2026-86145.md) | High | 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 |  |
| [CVE-2026-89157](https://patchblox.com/security/data/cve/CVE-2026-89157.md) | High | PCRE2 before 10.48, on 32-bit platforms, has a pcre2_pattern_convert out-of-bounds write when an attacker can provide a large pattern. | 8.2 | 0.0035 |  |
| [CVE-2026-89156](https://patchblox.com/security/data/cve/CVE-2026-89156.md) | High | PCRE2 before 10.48 has a pcre2_match out-of-bounds read after a JIT fallback when an attacker can provide invalid UTF data. | 8.2 | 0.0029 |  |
| [CVE-2026-89160](https://patchblox.com/security/data/cve/CVE-2026-89160.md) | High | PCRE2 before 10.48 has a pcre2_match out-of-bounds read during the PCRE2_MATCH_INVALID_UTF matching of an invalid UTF subject. | 8.2 | 0.0027 |  |
| [CVE-2026-89158](https://patchblox.com/security/data/cve/CVE-2026-89158.md) | High | PCRE2 before 10.48, on 32-bit platforms, has a pcre2_compile_32 integer overflow and resultant out-of-bounds write. | 8.2 | 0.0025 |  |
| [CVE-2026-89161](https://patchblox.com/security/data/cve/CVE-2026-89161.md) | High | 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 |  |
| [CVE-2026-89162](https://patchblox.com/security/data/cve/CVE-2026-89162.md) | Routine | libpcre2-16-0: In PCRE2 before 10.48, pcre2_serialize_encode might disclose two bytes to an adversary, typically in a situation wher... | 3.3 | 0.0016 |  |
