CVE-2025-58050

一、漏洞信息
 漏洞编号：[CVE-2025-58050](https://nvd.nist.gov/vuln/detail/CVE-2025-58050)
 漏洞归属组件：[pcre2](https://gitee.com/src-openeuler/pcre2)
 漏洞归属的版本：10.35,10.36,10.39,10.40,10.42
 CVSS V3.0分值：
  BaseScore：9.1 Critical
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
 漏洞简述：
  The PCRE2 library is a set of C functions that implement regular expression pattern matching. In version 10.45, a heap-buffer-overflow read vulnerability exists in the PCRE2 regular expression matching engine, specifically within the handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. This vulnerability may potentially lead to information disclosure if the out-of-bounds data read during the memcmp affects the final match result in a way observable by the attacker. This issue has been resolved in version 10.46.
