In the Linux kernel, the following vulnerability has been resolved: ext4: do not BUG when INLINEDATAFL lacks system.data xattr A syzbot fuzzed image triggered a BUGON in ext4updateinlinedata() when an inode had the INLINEDATAFL flag set but was missing the system.data extended attribute. Since this can happen due to a maiciouly fuzzed file system, we shouldn't BUG, but rather, report it as a corrupted file system. Add similar replacements of BUGON with EXT4ERRORINODE() ii ext4createinlinedata() and ext4inlinedata_truncate().
