- Summary
- ext4: don't set up encryption key during jbd2 transaction
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ext4: don't set up encryption key during jbd2 transaction
Commit a80f7fcf1867 ("ext4: fixup ext4fctrack_* functions' signature") extended the scope of the transaction in ext4unlink() too far, making it include the call to ext4findentry(). However, ext4find_entry() can deadlock when called from within a transaction because it may need to set up the directory's encryption key.
Fix this by restoring the transaction to its original scope.
