Vulnerability description
DayBreach CVE AI Research
CVE-2026-115865 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
