CVE-2026-107885 is a low-severity flaw (CVSS 3.3) affecting cups. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
OpenPrinting CUPS through 2.4.20 contains a resource-exhaustion vulnerability in the submission-timeout handling of cupsdCheckJobs(). The scheduler suppresses timeout processing for all pending jobs whenever any client connection has an in-flight Send-Document operation, without matching that connection to the job being examined. A client allowed to reach the IPP service can hold an incomplete HTTP request containing parsed Send-Document headers
Why this priority
