In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
btrfs: retry verity reads for not-uptodate Merkle folios<\/p>\n
btrfs_read_merkle_tree_page() can find a folio in the mapping that is not
\nuptodate. After taking the folio lock, the current code treats that state
\nas a read error and returns -EIO.<\/p>\n
That can make a previous transient read failure sticky. If the failed read
\nleft a not-uptodate folio in the mapping, later callers find that folio and
\nfail instead of retrying the read.<\/p>\n
Keep the existing page-cache insertion and locking order, but retry the
\nMerkle item read when a not-uptodate folio is found in the mapping. Also
\nunlock the folio when read_key_bytes() fails so that a later caller can
\nlock it and retry the read.<\/p>\n","protected":false},"excerpt":{"rendered":"
