CVE-2026-64157

A flaw was found in the Linux kernel's network file system (netfs) component. This vulnerability allows for incorrect handling of data during partial invalidation operations on streaming-write pages. An attacker could potentially exploit this to cause data corruption or unexpected system behavior, impacting data integrity.

This vulnerability is rated as Moderate because exploitation requires local authenticated access with standard user privileges and is restricted to causing data inconsistency or system instability rather than arbitrary code execution. The issue originates in the network filesystem (netfs) caching framework during partial invalidation of streaming writes. Red Hat Enterprise Linux 8 and 9 are unaffected as they lack the newer streaming-write implementation.
