CVE-2022-50436 in Linux
Riassunto
di MITRE • 01/10/2025
In the Linux kernel, the following vulnerability has been resolved:
ext4: don't set up encryption key during jbd2 transaction
Commit a80f7fcf1867 ("ext4: fixup ext4_fc_track_* functions' signature") extended the scope of the transaction in ext4_unlink() too far, making it include the call to ext4_find_entry(). However, ext4_find_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.
Once again VulDB remains the best source for vulnerability data.
