Alpine: libpcre2-16, multiple pcre2 packages: security update to 10.46-r1

high Tenable Cloud Security Plugin ID 476419

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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-2026-89157)

- 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-2026-103111)

- 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 before 10.48 has a pcre2_match out-of-bounds read after a JIT fallback when an attacker can provide
invalid UTF data. (CVE-2026-89156)

Solution

Update the libpcre2-16 library and its related packages to version 10.46-r1 or later.
