Description

This security bulletin contains information about 1 vulnerability.


1) Integer overflow (CVE-ID: CVE-2026-89157)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 5.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause memory corruption and a process crash.

The vulnerability exists due to integer overflow leading to an out-of-bounds write in pcre2_pattern_convert() when processing a very large attacker-controlled pattern using PCRE2-managed output allocation on a 32-bit system. A remote attacker can supply a specially crafted large foreign-syntax pattern to cause memory corruption and a process crash.

The issue occurs before pattern compilation or matching, and requires a 32-bit process with a non-NULL buffptr whose value is NULL.
