CVE-2022-50436 ext4: don't set up encryption key during jbd2 transaction

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...

CVE-2022-50436

CVE-2022-50436 : Linux kernel ext4 had a deadlock risk when ext4_unlink() extended the jbd2 transaction scope, because ext4_find_entry() could require setting up the directory encryption key inside a transaction. The fix restores the transaction to its original scope, preventing the deadlock. The...
