Detail

In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix to do sanity check for inline inode

Yanming reported a kernel bug in Bugzilla kernel [1], which can be reproduced. The bug message is:

The kernel message is shown below:

kernel BUG at fs/inode.c:611! Call Trace:
evict+0x282/0x4e0
__dentry_kill+0x2b2/0x4d0
dput+0x2dd/0x720
do_renameat2+0x596/0x970
__x64_sys_rename+0x78/0x90
do_syscall_64+0x3b/0x90

[1] https://bugzilla.kernel.org/show_bug.cgi?id=215895

The bug is due to fuzzed inode has both inline_data and encrypted flags. During f2fs_evict_inode(), as the inode was deleted by rename(), it will cause inline data conversion due to conflicting flags. The page cache will be polluted and the panic will be triggered in clear_inode().

Try fixing the bug by doing more sanity checks for inline data inode in sanity_check_inode().
