Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: remove clear SB_INLINECRYPT flag in default_options
In f2fs_remount, SB_INLINECRYPT flag will be clear and re-set.
If create new file or open file during this gap, these files
will not use inlinecrypt. Worse case, it may lead to data
corruption if wrappedkey_v0 is enable.
Thread A: Thread B:
-f2fs_remount -f2fs_file_open or f2fs_new_inode
-default_options
<- clear SB_INLINECRYPT flag
-fscrypt_select_encryption_impl
-parse_options
<- set SB_INLINECRYPT again
