CVE-2020-0407

In various functions in fscryptice.c and related files in some implementations of f2fs encryption that use encryption hardware which only supports 32-bit IVs Initialization Vectors, 64-bit IVs are used and later are truncated to 32 bits. This may cause IV reuse and thus weakened disk encryption...

CVE-2020-0407

The CVE-2020-0407 entry concerns Android kernel/F2FS encryption where hardware that supports only 32-bit IVs leads to truncation to 32 bits for 64-bit IVs in certain implementations. This IV truncation can cause IV reuse, weakening disk encryption and potentially enabling local information disclo...
