Remote unspecified impact via unpaused netfs subrequests
Published Jul 19, 2026 · Updated Jul 19, 2026
Incorrect error handling in Linux Kernel 6.12 through 6.18.33 and 6.19 through 7.0.10 allows remote attackers to cause unspecified impact. netfs_read_to_pagecache issues another buffered-read subrequest without first waiting when NETFS_RREQ_PAUSE is set or stopping when NETFS_RREQ_FAILED is set. No privileges or user interaction are required, but the published material does not identify a triggering filesystem or concrete consequence.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
