Уязвимости pcre2

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-2026-89161

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.

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-2026-89158

PCRE2 before 10.48, on 32-bit platforms, has a pcre2_compile_32 integer overflow and resultant out-of-bounds write.

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-2026-89156

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-2026-86145

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-2022-41409

Integer overflow vulnerability in pcre2test before 10.41 allows attackers to cause a denial of service or other unspecified impacts via negative input.

CVE-2022-1587

An out-of-bounds read vulnerability was discovered in the PCRE2 library in the get_recurse_data_length() function of the pcre2_jit_compile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers.

CVE-2022-1586

An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT.
