Updated mingw-pcre2 & pcre2 packages fix security vulnerabilities
Publication date: 09 Oct 2026Modification date: 09 Oct 2026
Type: security
Affected Mageia releases : 10
CVE: CVE-2026-86145 , CVE-2026-103111
Description
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-2026-86145)
PCRE2: out-of-bounds write in JIT matching with large stack allocations.
(CVE-2026-103111)
