Medium technical severity with public exploit material referenced by a structured source; prioritise exposed affected systems while verifying vendor guidance.
Alpine, Debian findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.
A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Patch availableThe PCRE2 library is a set of C functions that implement regular expression pattern matching. In version 10.45, a heap-buffer-overflow read vulnerability exists in the PCRE2 regular expression matching engine, specifically within the handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. This vulnerability may potentially lead to information disclosure if the out-of-bounds data read during the memcmp affects the final match result in a way observable by the attacker. This issue has been resolved in version 10.46.

The product reads data past the end, or before the beginning, of the intended buffer.
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may obtain information outside the intended access boundary.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.
CWE-125: Out-of-bounds Read. The product reads data past the end, or before the beginning, of the intended buffer.
