Vulnerability Title
f2fs: fix to do sanity check for inline inode
Source: NVD (National Vulnerability Database)
Vulnerability Description
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().
