Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-89160)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds read in pcre2_match() interpreter when processing invalid UTF subjects with PCRE2_MATCH_INVALID_UTF during backward character scans. A remote attacker can supply a specially crafted subject string to cause a denial of service.

Only patterns compiled with PCRE2_UTF and PCRE2_MATCH_INVALID_UTF are affected, and exploitation requires an invalid subject beginning with a UTF continuation code unit together with affected backward-walking pattern operations such as \X or variable-length lookbehind.
