pcre2-10.40-7.el9_8

The pcre2 package contains a new generation of the Perl Compatible Regular Expression libraries for implementing regular expression pattern matching using the same syntax and semantics as Perl.

Security Fix(es):

* pcre2: PCRE2: Out-of-bounds write allows arbitrary code execution via crafted regular expressions (CVE-2026-86145)
* PCRE2: PCRE2: Out-of-bounds read via invalid UTF data during JIT fallback (CVE-2026-89156)
* pcre2: PCRE2: Out-of-bounds write via large pattern input (CVE-2026-89157)
* pcre2: PCRE2: Denial of Service via out-of-bounds read during invalid UTF matching (CVE-2026-89160)
* PCRE2: PCRE2: Out-of-bounds write via integer overflow on 32-bit platforms (CVE-2026-89158)
* pcre2: PCRE2: Memory corruption vulnerability in pcre2_jit_match (CVE-2026-89161)
* pcre2: pcre2: Out-of-bounds write via crafted regular expression (CVE-2026-103111)

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.
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).
CVE-2026-89156
PCRE2 before 10.48 has a pcre2_match out-of-bounds read after a JIT fallback when an attacker can provide invalid UTF data.
CVE-2026-89157
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.
CVE-2026-89158
PCRE2 before 10.48, on 32-bit platforms, has a pcre2_compile_32 integer overflow and resultant out-of-bounds write.
CVE-2026-89160
PCRE2 before 10.48 has a pcre2_match out-of-bounds read during the PCRE2_MATCH_INVALID_UTF matching of an invalid UTF subject.
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.
