There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - In the Linux kernel, the following vulnerability has been resolved: netfs: Fix zeropoint update where
    i_size > remote_i_size Fix the update of the zero point[*] by netfs_release_folio() when there is
    uncommitted data in the pagecache beyond the folio being released but the on-server EOF is in this folio
    (ie. i_size > remote_i_size). The update needs to limit zero_point to remote_i_size, not i_size as i_size
    is a local phenomenon reflecting updates made locally to the pagecache, not stuff written to the server.
    remote_i_size tracks the server's i_size. [*] The zero point is the file position from which we can assume
    that the server will just return zeros, so we can avoid generating reads. Note that
    netfs_invalidate_folio() probably doesn't need fixing as zero_point should be updated by setattr after
    truncation or fallocate. Found with: fsx -q -N 1000000 -p 10000 -o 128000 -l 600000 \ /xfstest.test/junk
    --replay-ops=junk.fsxops using the following as junk.fsxops: truncate 0x0 0x1bbae 0x82864 write 0x3ef2e

    option. It shows read-gaps on folio 0x64 failing with a short read (ie. it hits EOF) if the FMODE_READ
    check is commented out in netfs_perform_write(): if (//(file->f_mode & FMODE_READ) ||
    netfs_is_cache_enabled(ctx)) { and no fscache. This was initially found with the generic/522 xfstest.
