Answer in brief
CVE-2026-115865 records a Unknown severity vulnerability in Starlet versions before 0.33 for Perl allow a request declaring a large Content-Length to kill a worker by exhausting memory. The current sources do not mark it as known exploited. The current feed maps Starlet (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Starlet versions before 0.33 for Perl allow a request declaring a large Content-Length to kill a worker by exhausting memory. The request body is read in a loop that asks sysread for all of the remaining declared length at once. Perl grows the read buffer to that size before any data arrives, so a length larger than available memory makes the worker exit with an uncatchable out of memory error before the application is called. A remote attacker can force a worker restart with each request of a few bytes.
