UBUNTU-CVE-2025-71201

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix early read unlock of page with EOF in middle The read result collection for buffered reads seems to run ahead of the completion of subrequests under some circumstances, as can be seen in the following log snippet:...

CVE-2025-71201

CVE-2025-71201 concerns the Linux kernel netfs subsystem, specifically a race/logic issue in buffered reads where read results could be collected beyond the intended EOF due to an end-check that used the file end rather than the folio end. The vulnerability manifests during asynchronous subreques...
