Vulnerability from cvelistv5
Published

Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN We found a few different systems hung up in writeback waiting on the same page lock, and one task waiting on the NFS_LAYOUT_DRAIN bit in pnfs_update_layout(), however the pnfs_layout_hdr's plh_outstanding count was zero. It seems most likely that this is another race between the waiter and waker similar to commit ed0172af5d6f ("SUNRPC: Fix a race to wake a sync task"). Fix it up by applying the advised barrier.

The attacker controls the triggering side of the race and the retry rate, so the condition is not beyond their influence.\nPR:N - The NFS client holds no authentication requirement over the server \u2014 the client authenticates to the server, never the reverse, and under the default AUTH_SYS there is no server authentication at all. No credentials or privileges on the target system are needed.\nUI:N - Exploitation needs only normal read/writeback activity on an already-mounted pNFS filesystem (fstab, autofs, cloud NFS), which happens continuously without any victim action. No mount or file operation must be induced at exploit time.\nS:U - The lost wakeup hangs kernel tasks within the same security authority as the affected client kernel. No VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is a missing memory barrier before wake_up_bit(); no memory is read out of bounds, freed, or exposed. No data is disclosed.\nI:N - No memory is corrupted and no data is modified \u2014 the task simply never wakes. There is no write primitive or control-flow influence.\nA:H - The waiter in pnfs_update_layout() sleeps indefinitely while holding the page lock, and other writeback tasks then block uninterruptibly on that same page lock, wedging writeback across the system as observed in production. This is a permanent hang producing hung-task watchdog splats and a panic when hung_task_panic is set."
