CVE-2025-38393

Severity CVSS v4.0:
Pending analysis
Type:
CWE-362 Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN<br /> <br /> We found a few different systems hung up in writeback waiting on the same<br /> page lock, and one task waiting on the NFS_LAYOUT_DRAIN bit in<br /> pnfs_update_layout(), however the pnfs_layout_hdr&amp;#39;s plh_outstanding count<br /> was zero.<br /> <br /> It seems most likely that this is another race between the waiter and waker<br /> similar to commit ed0172af5d6f ("SUNRPC: Fix a race to wake a sync task").<br /> Fix it up by applying the advised barrier.
