Amazon Linux 2023: CVE-2025-38393: Important priority package update for kernel (Multiple Advisories)

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.
