The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - btrfs: do not WARN_ON() if we have PageError set Whenever we do any extent buffer operations we call     assert_eb_page_uptodate() to complain loudly if we're operating on an non-uptodate page. Our overnight     tests caught this warning earlier this week WARNING: CPU: 1 PID: 553508 at fs/btrfs/extent_io.c:6849     assert_eb_page_uptodate+0x3f/0x50 CPU: 1 PID: 553508 Comm: kworker/u4:13 Tainted: G W 5.17.0-rc3+ #564     Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.13.0-2.fc32 04/01/2014 Workqueue: btrfs-cache     btrfs_work_helper RIP: 0010:assert_eb_page_uptodate+0x3f/0x50 RSP: 0018:ffffa961440a7c68 EFLAGS: 00010246     RAX: 0017ffffc0002112 RBX: ffffe6e74453f9c0 RCX: 0000000000001000 RDX: ffffe6e74467c887 RSI:

It didn't keep us from continuing to use a buffer     that we already had found. In this case we're searching the commit root to cache the block group, so we     can start committing the transaction and switch the commit root and then start writing. After the switch     we can look up an extent buffer that hasn't been written yet and start processing that block group. Then     we fail to write that block out and clear Uptodate on the page, and then we start spewing these errors.
    Normally we're protected by the tree lock to a certain degree here. If we read a block we have that block     read locked, and we block the writer from locking the block before we submit it for the write. However     this isn't necessarily fool proof because the read could happen before we do the submit_bio and after we     locked and unlocked the extent buffer. Also in this particular case we have path->skip_locking set, so     that won't save us here. We'll simply get a block that was valid when we read it, but became invalid while     we were using it. What we really want is to catch the case where we've read a block but it's not marked     Uptodate. On read we ClearPageError(), so if we're !Uptodate and !Error we know we didn't do the right     thing for reading the page. Fix this by checking !Uptodate && !Error, this way we will not complain if our     buffer gets invalidated while we're using it, and we'll maintain the spirit of the check which is to make     sure we have a fully in-cache block while we're messing with it.
